• Alternative software for Pinnacle PCTV 100e

  - by Stijn Sanders

  I have a Pinnacle PCTV 100e external USB cable television receiver. I've been using Pinnacle's software that came with the card (TVCenter Pro) to record things at given times. Things I don't like is an extremely high CPU load, and that it doesn't seem to halt the screensaver from running when watching in full screen. Also, I was away the last two weeks, and the schedules went terribly bust. Some items were recorded hours before or after the actual scheduled time (and now I missed some shows), and some recurring schedules weren't converted into the next occurrence correctly! Is there good alternative software that would work with my PCTV 100e? (Preferalby cheap or free) I've tried VLC Player, which gets video, but no audio. I've tried MediaPortal, which crashes when trying to scan for channels. When I select a channel manually, the stored mpg has big errors in encoding and is also missing audio. There's VirtualDub, but that doesn't have ready-made scheduled-recording options. This I can conjure some scheduled scripts for, but I've noticed the sync gets awfully wrong after some time. I've tried Windows Media Center, but it doesn't seem to support the PCTV 100e.

• 13" MacBook Pro with Win 7 and External VGA gets 640x480

  - by Jim McKeeth

  I have a brand new 13" MacBook Pro - 2.26 GHz and the NVIDIA 9400M Video card. I installed Windows 7 (final) in boot camp and booted up to Windows 7. Installed all the drivers from the Apple disk and it was working great. Then I attached the external VGA adapter (from apple) to connect to a projector and it dropped down at 640x480 resolution. No matter what I did it wouldn't let me change to a higher resolution if the external VGA was connected. Once it disconnects then it goes back to the normal resolution. If I am booted into Snow Leopard it works fine. I tried updating the NVIDIA drivers and it behaved exactly the same. Ultimately I want to get 1024x768 or better resolution when connected to an external display. If it isn't fixable then I am curious if anyone else has seen this, if it is a known issue, and who to contact for support (Apple, Microsoft or NVIDIA?) Update: Just attaching the Mini-DVI to VGA adapter kicks it into 640x480, no projector is required. I tried forcing the display driver from Generic PnP Monitor to one that supported 1024x768 and that didn't work either.

• Media Center setup won't complete for watching TV

  - by Robert

  I have a problem watching TV in Media Center. The TV constantly pauses 1/2 second then plays 1 second, pauses 1/2 second, plays 1 second - it is constant and does not vary. This problem occurs on all channels, live or recorded. The bottom 5th of the screen is solid green. I know the problem is Media Center because I can use Pinnacle's TVCenterPro to watch TV and there is no skipping/pausing (and not green on bottom). I was using cable, and switched to DirecTV (satellite). Trying to do "Set up TV signal" in Media Center seems to be what broke it. I get an error "IR Hardware not detected." I can use the remote to "try again" - so the IR hardware works fine (Media Center's remote/sensor). I tried plugging the IR Blaster into both ports, and I tried a different USB port for the IR receiver. I can't complete the setup. Media Center was playing TV okay (with the new DirecTV) before I tried to run setup. (I ran setup to try to do recording with Media Center.) Hardware/Software: Pinnacle PCTV 800i HD PCI card (coax cable from DirecTV tuner), ATI Radeon HD 3200 Graphics, Windows XP SP3 Media Center Edition, AMD Athlon Dual Core 2.5 GHz, 1.75 GB RAM.

• Philips Monitor problems - vertical lines on screen

  - by asdasd

  I have an old CRT Philips Monitor 17'' and it was working well. There were problems with the electrical power and the monitor started to make some sound and a smoke was getting out of it. I quickly switched it off the power, and in the morning when the power was ok i started the monitor and it appeared to be working and it worked for a couple of minutes when i find out some smell was coming from it, and after 5 minutes the screen i was working shut down and on the monitor some vertical lines appeared - and nothing else. I thought it was the OS, so i rebooted the pc and while it was booting i realized the monitor didn't show the bios info etc, but the same vertical lines on the whole screen were on it, sometimes their color was changing and they were blinking, but no screen appeared - only those vertical lines. After a day, the monitor was ok again - i turned it on and no there were no lines, everything was working fine. The same for the next 2 days. My question is: If anyone had ever had the same problem, can you help me ? THe monitor may be ok now but i am afraid it can get back those lines again. I don't know what to do, if you know please tell me whether should i take it to the service or not. Thank you.

• How to calculate RAM value on performance per dollar spent

  - by Stucko

  Hi, I'm trying to make decisions on buying a new PC. I have most specifications (processor/graphic card/hard disk) pin-downed except for RAM. I am wondering what is the best RAM configuration for the amount of money I'm spending. As the question of best is subjective, I'd like to know how would I calculate the value of RAM sticks sold. 1.(sample)The value of amount of memory: 1) CORSAIR PC1333 D3 2GB = costs $80 2) CORSAIR PC1333 D3 4GB = costs $190 would it be better to buy 2 of item 1) instead of 1 of item 2) ?? Although I would normally choose to have 1 of 2) as the difference is only (190-(80*2)) = 30 as I would save 1 DIMM slot, What I need is the value per amount: 1) 80/ 2 = $40 per 1GB 2) 190/ 4 = $47.5 per 1GB 2. The value of frequency: 1) CORSAIR PC1333 4GB = costs 190 2) CORSAIR PC1600C7 4GB = costs 325 Im not even sure of the denominator ... $ per 1 ghz speed? 3. The value of latency: 1) CORSAIR CMP1600C8 8-8-8-24 2GBx3 (triple channel) = costs 589 2) CORSAIR CMP1600C7D 7-7-7-20 2GBx3 (triple channel) = costs 880 Im not even sure of the denominator ... $ per 1 ghz speed? Just for your information i'd like to get the best out of the money im going to spend to put on a 6 DIMM slot i7core motherboard.

• Digitize video?

  - by kire

  I got some movies on a VCR that i want to move to my computer somehow. (for personal use) I have a video capture card and all hardware required. I'm looking for the software - programs, codecs etc. I like the format that most torrents come in and got some of these i'd like to use as reference for comparison. How can i see what codec, bitrate, etc a movie is using so i can pick this and know that it will work and look good. For AVI-files the bitrate is visible in explorer but it doesn't mention the codec used and i also have a lot of MKV-files that explorer can't handle. All kinds of tips, tricks and other suggestions are welcome. This is completely new to me. How do I avoid that video/audio gets out of sync for example, many movies you download have audio out of sync so i guess this can happen quite easily. The encoding-program has to run on windows and for playback the movies should work on at least VLC for windows.

• How would I setup iMail to forward a user's mail to another service w/o leaving a copy locally?

  - by Scott Mayfield

  I have an iMail 2006 server installation in which I have a particular user that has several aliases that all point to a single user (me, for the record). I've been copying all of my mail to GMail and reading it there, but it annoys me that I have to go back weekly and log into my mail account on iMail and delete between 6 and 10 thousand copies of messages I've already received, in order to keep my mailbox from filling up (yes, I have it set with no quota, but I consider it bad form to just let the box grow indefinitely). I've got the copying setup via an inbound user rule, but I'm wondering how to accomplish a "copy and delete" rule. The manual isn't clear on what happens with multiple matching rules (will they be processed in order, or is it a first match situation?) and there isn't a means to combine multiple actions into a single rule. If I use the "forward" action, I THINK that it's going to screw up all the sender information once the mail reaches my GMail account and show it as coming from me instead of the original senders (can anyone confirm that this is accurate?) An easy answer would be to delete my user account entirely, replace it with an alias that maps to my GMail account, but then I would lose my ability to log into the system for admin duties. So that leads me to creating a second, lesser known account for admin use, but since it's a real account, sooner or later I'm going to get mail sent to it and I'll be back to the same situation of having a user account that doesn't get emptied periodically. I imagine I can set the quota to 0 MB to cause all incoming mail to my admin account to bounce, or setup an inbound rule to bounce everything, but this is starting to sound kludgy to me. Does anyone know of a more direct work around to copying a user's incoming mail to an outside server and then deleting the local copy w/o removing their account entirely? Or is this just wishful thinking? Thanks in advance. Scott

• Windows XP can't connect to wireless network

  - by mikez302

  I have a desktop computer with a wireless card, running Windows XP SP3. For a little while, I had a remote network connection set up for my job, but I didn't need the remote connection so I deleted it. Now, I am unable to connect to the internet at all from that computer through my wireless router. I can connect through my router using my laptop, and I can connect through my neighbor's router using my desktop, but for some reason I can't connect through my own router using my desktop. I see the "Wireless Network Connection 5" icon in my system tray, but it tells me it is not connected. When I click on the icon, I see a list of wireless networks, including my own, which is set up to automatically connect, although it doesn't. When I try to connect to my network on my own (by clicking on it, then clicking "Connect"), it asks me for my network password like it usually does. I see a box come up saying "Waiting for network to be ready..." and it hangs there. On the list of wireless networks, my network says "Acquiring network address" but it doesn't actually connect. How can I fix this? I tried rebooting my computer, repairing my connection, and restarting my router, and I am still having this problem.

• Can Xen be configured to dedicate only one port of a dual-port NIC to a domU?

  - by jamieb

  I'm using CentOS 5.4 on my dom0 with a stock Xen kernel. I'm attempting to use the pciback module to hide some of the Ethernet ports from the host and reserve them for a domU I intend to use for a firewall (process described here). However, when I launch the domU, I get the following error message: Using config file "/etc/xen/firewall". Error: pci: improper device assignment specified: pci: 0000:01:04.0 must be co-assigned to the same guest with 0000:01:06.0, but it is not owned by pciback. lspci gives me the following output: 00:00.0 Host bridge: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub (rev 02) 00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02) 00:1d.0 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #1 (rev 01) 00:1d.1 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #2 (rev 01) 00:1d.2 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #3 (rev 01) 00:1d.3 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 (rev 01) 00:1d.7 USB Controller: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller (rev 01) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1) 00:1f.0 ISA bridge: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge (rev 01) 00:1f.2 IDE interface: Intel Corporation 82801GB/GR/GH (ICH7 Family) SATA IDE Controller (rev 01) 00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 01) 01:04.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

• NTFS partition size not recognized after disaster recovery clone

  - by djechelon

  I'm in the middle of a disaster recovery of a 250GB hard disk that was "clicking". Obviously I didn't have a backup copy. I managed to salvage all the files thanks to GParted Live that was able to read the disk without a single "click" sound. So I cloned the partition to a new drive sized 500GB. Unfortunately, GParted process went to some kind of infinite loop, disks stopped I/O and after a couple of hours I interrupted the clone process I started. Now the problem is: when cloning the partition I also chose to expand 250GB to the whole 500GB of the target disk. Windows sees the partition sized 500GB in computer management, but Windows Explorer only sees 250. chkdsk e: /f says the filesystem is OK. How can I repair the file system and let Windows see the full 500GB of the new partition? An alternate idea is to deep-copy the files from the backup disk to a newly formatted disk. This should definitely fix. Any other ideas?

• Cannot connect with Cisco VPN but can connect with ShrewSoft VPN

  - by rodey

  EDIT: We connected an air card to the computer to use a different Internet connection and using the Cisco software, we were able to successfully connect to our VPN server. I just don't understand why the ShrewSoft VPN client would connect but the Cisco connection won't. I'm not our network admin so sorry if I butcher some of the terminology. I have a computer at remote site that connects to our network through Cisco VPN. It uses the Cisco VPN software to do so. The problem is that the computer at this site cannot connect to our VPN because it is getting error "Reason 412: The remote peer is no longer responding." To see if perhaps something on their network was blocking the connection, I installed the ShrewSoft VPN client on the computer, imported our .pcf file and connected with no problem. I have tried two different versions of the Cisco VPN software (4.8.0.* and 5.0.03.*) and have the same problem. I installed Wireshark on the computer and have confirmed (while trying to connect through Cisco) that the computer is trying to contact the VPN server but is not receiving a response. We are not having any other problems regarding users not being able to connect. I'm at a loss at what else to check. I'll be monitoring this and have access to the computer at any time.

• Is Gmail Being Blocked by my ISP (wait till you read this)?

  - by James

  This is the strangest thing I have ever encountered. I have a desktop on which I cannot access Gmail and also youtube sign in (I believe since youtube is owned by google they both use the same sign in system). So okay, maybe my ISP is blocking these for some reason or maybe my firewall is, or maybe there is something wrong with my connectivity, right? NO. On other computers that uses the same connection via a wireless router I can access both gmail and youtube sign in just fine. On this computer which doesn't have a wireless card and so I have to connect via Ethernet cable (connected to a USB converter since the Ethernet port doesn't work anymore) I can access all sites and services including things like aol and hotmail. But only when it comes to gmail, do I get complete and utter throttling. I even turned off my AV ad Firewall momentarily and no luck. The gmail ages starts to load and by mid point it just stays there loading and loading and loading... never ends. I tried everything, I reset the modem and router multiple times. I reinstalled my operating system from a vista to a windows 7 hoping a complete reinstall would solve the issue, but no luck. So can anyone for the life of them figure out why this could be? And yes, I am going to call my ISP but not to solve this issue, but to cancel them. I want to upgrade to cabel from DSL anyway. I didn't mention my ISP because I'm not sure if that is within the rules (if it's okay some one let me know and I will). P.S. All this happened one day, before gmail was perfectly accessible in this computer. I can't remember anything special that happened on that day prior to this. The only thing I can think of is, my ISP or Google itself is blocking this computer based on it's mac address, but I don't know if that's even done. Additional info: PC: Windows 7 Ultimate 32 bit Connection Type: DSL Connecting Medium: Ethernet cable via USB converter

• Apple / Mac OS X - Is there a Package Manager like Linux

  - by Walter White

  I am a Linux/UNIX user and love the package management that comes with it. For the most part, I like Ubuntu, but just like anything else, it is the minor things that you live with daily that would be nice if they just worked. My main issue is my wacom tablet while it works, every time there is an OS update, I have to rebuild the wacom driver. The other slightly annoying issue is, my ATI video card is not fully supported. When I use the HDMI out, the sound doesn't go through it, and the screen is not entirely used. I would happily get an Apple if it had a similar package management system like Ubuntu, Gentoo, or other Linux distribution. This takes the work out of getting the latest enhancements or fixes. It also takes all the guess work out about what you need to get something to work. I just want to use my computer, not administer it. Aside from Apple applications, if I wanted to install the GIMP on an apple, would it go and fetch ufraw if I wanted support for that and whatever other dependencies GIMP has? If I want Netbeans installed, will it go and get a JDK and maven if I want that? If not, is there something in the works? I know I don't update my applications that frequently, but that is mainly because I'm not aware of the updates. The updates all happen in the background. Walter

• Windows Remote Desktop: "configuring remote session" closes without error

  - by icelava

  I have a desktop/laptop pair at home operating x64 Windows 7 (the desktop was upgraded from Windows Vista, works just fine). I remote desktop to them on a daily basis when outside. In recent weeks, I would occasionally fail to connect to my desktop. It can connect and authenticate fine, but the "configuring remote session" dialog would simply close and not show me the desktop window or any error message. There is no error event log relating to this on the desktop computer. Some suggestions call for disabling remote audio, which mine already is, but trying different audio modes did not yield any different result. I am not too sure if this is related to video card drivers (they do get auto-updated), since remote desktop video is supposed to steer via a virtual device driver? Nonetheless the desktop operates three monitors via an ATI Radeon HD5770 (1 Displayport, 2 DVI). I do not see a real problem with that since I can mostly connect and operate it remotely. I try to "remote tunnel" via my home laptop but obviously won't work either as the problem lies in the desktop. What other conditions can cause remote desktop to break without error? UPDATE I came home and still couldn't connect to the desktop until I restarted the entire system.

• Windows 7 x64 RTM USB Port Has Power But Won't Recognize Mouse/Keyboard/Anything

  - by ben

  I have an odd error that doesn't seem to fit in with any of the other odd Windows 7 x64 USB errors that have been kicked up on Google. Here we go: Uninstalled Tortoise SVN and clicked restart computer. My machine had been up for around 28 days On reboot my mouse and keyboard failed to work anymore, couldn't log in. Tried every USB port I have on my Dell 390 and the ports on my Dell 19's, nothing worked. They had power but Windows would not respond when I manipulated the keyboard/mouse. Rebooted my computer and pressed F2 to get into bios, my keyboard is working fine in bios. Keyboard and mouse work fine on other computers when using USB. Found adapters for keyboard and mouse to convert from USB to PS/2 ports, works fine. I'm actually typing this question on the same keyboard, same computer, just using PS/2 ports for my mouse and keyboard. It appears to be a Windows 7 x64 issue. Other things I have tried: Multiple other mice and keyboards, iphone, all with no luck. Each one gets power, but Windows never tries to install drivers or sees that they are connected. Uninstall and reinstall all USB drivers. Drives uninstall and reinstall fine and report no errors in Control Panel. In Power Management I disallow Windows from turning off USB ports to save power Installed the latest nVidia drivers for my graphics card, no change. Anyplace else I can look/try? Thanks!

• my X server doesn't load a module called "glx", but my video drivers seem to be installed

  - by rumtscho

  I just got a new, very wide monitor (2560x1440) and there is no sense maximizing my applications. So I installed Compiz Config Settings Manager and enabled Grid. Nothing happened, the shortcuts don't move application windows. Went to System - Preferences - Appearance, the Visual effects tab. It at "disabled". When I try to set them to "normal" or "extra", a message box appears telling me that it's searching for video drivers, then disappears, and I get an error message "Desktop effects could not be enabled". I opened Xorg.0.log, and had errors there: (EE) Failed to load /usr/lib/xorg/modules/extensions//libglx.so (II) UnloadModule: "glx" (EE) Failed to load module "glx" (loader failed, 7) (II) LoadModule: "extmod" Going to Administration - System - Hardware drivers, it said that there are no available and/or installed hardware drivers. But apt-get said that it cannot install nvidia-glx-185, as it is already installed. Googling my error message suggested that I install and run something called envyng. This let me install the nvidia drivers again, and now I can see in the Hardware Drivers window that they are installed and active. But the error message in Xorg.0.log remains, and I still cannot enable the Compiz effects or use Grid. Now, I don't have enough Linux experience to understand if this is a single cause-effect-chain of problems, or three independent ones, but I'd appreciate help for any of them. I am running Ubuntu 9.10, the video card is a GeForce 7600GS.

• How do I improve my screen resolution in Windows Remote Desktop?

  - by Jeff

  I'm RDP'ing into a Win2K3 machine from a WinXP machine, and I cannot stand the low screen resolution I get on the Win2K3 box. Text is too large and the graphics/colors aren't very smooth. How do I improve this? If I right-click on the desktop of the remote machine and go to Properties - Settings, I see that the screen resolution is set to 1280x1024 (should be okay, I would think), and the color quality is Medium (16 bit) (not optimal) and I don't have the option to change either setting (because they're set in the .rdp file for the session, right?). If I move over to the Appearance tab, I see that font size is set to Normal, with no option to make it smaller. The thing is, these settings are close to what I have on the XP machine I'm RDP'ing in from. The only difference (in those settings) is the color quality, which is 32 bit. Any ideas on how I can improve the situation? Other tidbits: The graphics card on the Win2K3 machine is ATI ES1000. I think I have the latest drivers for it. I'm running VMware Workstation on the Win2K3 machine, and if I create a Win2K3 VM and RDP into it from the XP machine, the resolution is just fine.

• Monitor reset itself and now I can't set the resolution/settings back to how it was before

  - by verve

  I've had my LG 24" widescreen monitor since 2009 and 2 weeks ago I noticed the monitor turned itself off (never had it done this before) so I switched it back on to find all the settings like gamma, resolution etc. different = looked like it had been reset. Everyone in the house swears they never unplugged and plugged it back in. When I opened a webpage the fonts and zoom on the pages were different and my desktop was strange too; fonts of the icons were different etc. The screen seems blurry and when I watch movies the faces look distorted so I thought I would try to first figure out the resolution it used to be but when I go under "Adjust screen resolution" none of the options work and there is no recommended resolution marked; all the options stretch out the screen and looks terrible so right now I have it set to the least distorted one. Then since the resolution wasn't working I set the other manual settings(done by physical buttons on the monitor) back to how it used to be (luckily, I had written these down). The monitor looks better but the resolution makes it a strain to use. I thought maybe some Windows update caused this crap so I tried to System Restore: didn't work. What went wrong? A few questions: 1) What was the likely cause of the monitor shutting down itself and screwing up the settings I have been using since the day I bought the monitor? 2) Why have the fonts changed everywhere unless this is a HDD/video card problem? 3) How do I find the perfect resolution it used to be? The monitor wants me to set it to 1920 x 1080 but that isn't one of the options although I don't remember what resolution I used before. I use the 16:9 setting while I try the available resolution options but nothing looks good! How do I find what it used to be?

• Enabling hardware acceleration and Xinerama for multi-monitor/multi-GPU in Linux

  - by mynameiscoffey

  My current setup is three monitors connected as follows (monitors listed from left to right): GPU0 (nVidia GTX 280): - Dell 2405FPW (1920x1200) - Dell U2410 (1920x1200) GPU1 (nVidia 210): - Dell 2405FPW (1920x1200) Works like a charm in Windows 7, not so much in Linux. I seem to only have three real options: Run all three monitors as a seperate X screen, I get hardware acceleration but as they are all independent X sessions I cannot move windows between them and can only have firefox open on one at any given time. Run the two on GPU0 in TwinView mode and have GPU1 as a seperate X screen. Same limitation as 1 but at least two monitors work together ok. I did have an issue where occasionally Linux saw both monitors on GPU0 as a single large monitor however. Enable Xinerama and have everything work as I want it to but hardware acceleration is gone and the display is Windows 95 style choppy. My ideal solution would be to have all screens working as they do under Xinerama without the limitation of having hardware acceleration disabled. I don't even care if that means rendering all three on GPU0 and somehow farming out the display of the third monitor to GPU1, whatever works. My question is this: is there any way to accomplish this? I don't feel like my use case is so out there that there shouldn't be at least some form of support (beyond the three limited options presented above), or is my best option going to be to just suck it up and pick up a better card to replace both that can handle three outputs by itself?

• Reliable applicance for routing IT emergency calls (SIP and ISDN)

  - by chiborg

  We have a fairly big IT installation and our IT staff needs to be reachable 24/7. At the moment we have the following setup for "emergency" calls to our IT staff on our main Asterisk box: An incoming emergency number (connected via SIP trunk and a BRI card in case the SIP trunk goes down). When the number is called during the office hours, all the SIP phones of the IT staff are called simultaneously. When the number is called out of office hours interface, a list of mobile phone numbers is called, one after another until someone picks up. The list can be changed by the IT staff via command line script. The setup works well, but the Asterisk is heavily used in a call center, has experienced some outages and misconfigurations, each of them bringing down the IT emergency number. So we'd like to put the IT emergency call functionality on a separate device. This does not need to be a big server, it even does not need to be Asterisk, it only has one purpose and should do it reliably. It should be very low-maintenance. Any suggestions for hard- and software?

• Probability of Blade Chassis Failure

  - by ChrisZZ

  In my organisation we are thinking about buying blade servers - instead of rack servers. Of course technology vendors also make them sound very nice. A concern, that I read very often in different forums, is, that there is a theoretical possibility of the server chassis going down - which would in consequence take all the blades down. That is due to shared infrastructure. My reaction on this probability would be to have redundancy and by two chassis instead of one (very costly of course). Some people (including e.g. HP Vendors) try to convince us, that the chassis is very very unlikely to fail, due to many redundancies (redundant power supply, etc.). Another concern on my side is, that if something goes down, spare parts might be required - which is difficult in our location (Ethiopia). So I would ask to experienced administrators, that have managed blade server: What is your experience? Do they go down as a whole - and what is the sensible shared infrastructure, that might fail? That question could be extended to shared storage. Again I would say, that we need two storage units instead of only one - and again the vendors say, that this things are so rock solid, that no failure is expected. Well - I can hardly believe, that such a critical infrastructure can be very reliable without redundancy - but maybe you can tell me, whether you have successfull blade-based projects, that work without redundancy in its core parts (chassis, storage...) At the moment, we look at HP - as IBM looks much to expensive... thanks a lot best regards Christian

  Hi, I'm having a problem with my desktop whereby it sometimes resets itself semi-randomly. For example, I'll switch it on, it'll boot an OS and shortly after getting to the desktop it will immediately reset with no warning. The time isn't consistent - sometimes it does it before reaching login. I'm pretty sure it's not an OS thing; have tried Ubuntu and a Windows install and both exhibit it. It also doesn't appear to be heat-related because sometimes it appears to be able to "get past" it and will then run stably even under load; if anything it seems to be worse from a cold start. My gut feeling is some kind of power issue but I'm clutching at straws a little. Any suggestions on how I could go about testing it or trying to narrow the problem down would be appreciated. The machine is four years old now so while I can replace components if needed, it's not worth enough that I'm comfortable buying new parts without being pretty confident that they'll fix the problem. Thanks in advance for any help :) Edit: Okay, the motherboard is a MSI K8N SLI; CPU is an Athlon64 X2 4200+. Has one video card, a GeForce 7800GT. 1GB RAM, not sure of brand; 3 hard drives, two SATA and one PATA. Flashed motherboard to latest BIOS some time ago. Edit the Second: I thought I'd narrowed it down to the PSU for a while, but then it recurred again. I ended up pulling everything out but CPU, RAM and motherboard and it still seems to be stuffed (if anything, it's gotten worse in the last couple of days). I assume it's one of those three components, but the machine is old enough that I don't really want to spend money replacing any of them. So thanks for everyone's suggestions; much appreciated!

• Cheap desktop computer in 19" rack-mountable form-factor?

  - by Alex Basson

  I'm a high school teacher at a small private school. As of this year, we have SMARTBoards in every classroom (though I've had one in the class I share for two years now). The classrooms themselves don't have computers in them, so we teachers bring our laptops to class and connect them to the boards. This has several disadvantages: This takes a few minutes while we wait for the board to boot up and then orient the board to our individual laptop -- we have to do this every time b/c different teachers have different laptops requiring different orientations. This isn't ideal because when you only have 43 minutes per class period, waiting five minutes just to get started is a real waste. Carrying your laptop to class doesn't sound so bad until you consider that we're also carrying textbooks and piles of student papers, and we're carrying it all through crowded high school hallways. More than one laptop has fallen THUNK to the floor, with dire consequences. We feel we could eliminate the need to use our laptops with the SMARTBoards if we had a dedicated computer in each classroom hooked up to the board at all times. Each board set-up is connected to a podium with a standard 19" rack in it, currently housing a power supply and DVD player. There're plenty of rack spaces available. So I'm thinking: maybe we could get some inexpensive computers in a 19" rack-mountable form factor, install them in the podiums, and connect them to the boards on a permanent basis. Any suggestions?

• How to fix Quicktime video color problems on nVidia chipset and Windows XP?

  - by Matthew Glidden

  My laptop frequently plays video as if in very low-color mode. Though the sound remains clear, it looks terrible, showing only a few shades of red, blue, or yellow. (It's even worse than 8-bit color.) The problem doesn't happen consistently, so I'm looking for troubleshooting advice or known solutions. I use a Dell Latitude D620 laptop with Windows XP, on-board nVidia video chipset, Quicktime, and multiple monitors (laptop screen + VGA-connected LCD). Color problems happen in each application I tried, iTunes, a browser, and the Quicktime standalone player. It doesn't happen right after reboot, so could be from a sleep-wake cycle, or at least being on for an extended period. Google results suggest reinstalling nVidia drivers, which I've done several times with no change. I have found 2 workarounds. Reboot, sacrificing significant time and disrupting work In nVidia control panel, change color to 16-bit, and then back to 32-bit This happens with all video playback, so it's definitely not one corrupt file. I use workaround #2 consistently, but would love a longer-term solution.

• Wireless to Wireless Transfer Slow on a Linksys WRT54GL

  - by Kyle Brandt

  The Situation: When I try to transfer a file from one computer to another that are both connected via wireless on a WRT54GL (in a office) with dd-wrt firmware I often get bad speeds. In generally they average around 100 kilobytes a second. Either computer can download via wireless from the Internet at at about 2 megabytes a second. The speed is slow with the transfer of one large file. There are about 20 other wireless networks that the computers can see, so there is a lot of noise, but I don't have the equipment to really monitor the frequencies well. But that still seems pretty slow. I thought maybe it was the transmit on each card, but even when they are 5 feet away with a line of sight I still get these speeds. According to Linux both cards are operating at 54g. My Questions: Is this normal for this sort of consumer level wireless equipment? Anything I can do to improve it? why is wireless to wireless transfer slow when everything else isn't? Whats steps might I take to figure out what is happening? For example, are lots of packets not making to the access point requiring retransmissions? Above all, I want to find out what the problem actually is. This may seem odd, but at this point I am more interested in understanding what the problem is than fixing it. What I have tried: I have tried messing with lots of settings. Different channels, xmit power, G-Only, none of which has made anything any better. I've also tried upgrading to newer dd-wrt firmware version and doing a reset to wipe out the settings.
