• Overheating computer

  - by Samurai Waffle

  My computer overheats somewhat frequently, usually during intense use. And by intense use I mean browsing the internet while downloading, or gaming. It even overheats on extremely old games though, Master of Orion 2, which was developed for Windows 95. My computer has a Pentium 4 Ghz processor, 2 GB of ram, and is running Windows XP. One of the symptoms it has after overheating, is that it'll turn on immediately afterwards, but won't show any video on my monitor. I usually have to wait at least 5 minutes (mostly at least 10) before I can get it to turn on and show video on my monitor. I also usually have to wiggle around the graphics card a little bit, which is the ASUS A9550 Series with 256 MB. I'm not sure exactly what is causing the computer to overheat. At first I thought it was the video card, but after I noticed it was doing it while playing Master of Orion 2, I'm not so sure, because that game can't be making the video card work all that hard. So how exactly can I pinpoint the problem? Thanks for any help provided. Edit: Okay I downloaded the programs that you specified, and will start benchmarking my system to try and pinpoint what's overheating. What is the temperature range for when it's getting to hot? Also I have an abundant amount of software experience with computers, but unfortunately not to much hardware experience.

• ATI gpu (video accel, decode, encode, ATI Stream, DXVA)

  - by Shiki

  Okay its a long question title for sure. I'm looking for a new video card (yes,SU is not a page for that, but wait). I've been a loyal NVidia customer ever since, now using a 8600gts. Old but still somewhat good, its a bit slow though. I want an upgrade because 8600gts wont support better vdpau and new features. I checked out the prices and the documents, I would need a GTX260 card. Which costs ..well.. a lot. ATI performs much better for that price. (At least on every test it outperforms GTX260). However, as far as I know there is no gpu accel with ATI. The things you can use is DXVA only, no other method. Could you correct me out there? Will be there a gpu accel for ATI also? Or is there one available? (DXVA is not bad, but kinda slow compared to NVIdia's CUDA.) What about openCL? How does ATI support that? (I'm talking about the 5850 ATI card at the minute, I would buy that instead of the NVidia.)

• Parallel port blocking

  - by asalamon74

  I have a legacy Java program which handles a special card printer by sending binary data to the LPT1 port (no printer driver is involved, the Java program creates the binary stream). The program was working correctly with the client's old computer. The Java program sent all the bytes to the printer and after sending the last byte the program was not blocked. It took an other minute to finish the card printing, but the user was able to continue the work with the program. After changing the client's computer (but not the printer, or the Java program), the program does not finish the task till the card is ready, it is blocked until the last second. It seems to me that LPT1 has a different behavior now than was before. Is it possible to change this in Windows? I've checked BIOS for parallel port settings: The parallel port is set to EPP+ECP (but also tried the other two options: Bidirectional, Output only). Maybe some kind of parallel port buffer is too small? How can I increase it?

• Dual VGA monitors with Quadro FX 580?

  - by dentrasi

  I have a machine with a Quadro FX 580 card (DVI and two Displayport). Attached to it are two 19" Acer screens, which are both (annoyingly) VGA. The first one works perfectly, with a DVI-VGA adaptor. The second one doesn't work. It's got a VGA cable, which goes into a VGA-DVI converted, which then goes into a DVI-Displayport converter. Initally, I was getting 'Cable Unplugged' on the screen, and it couldn't be seen by Windows or the nVidia control panel. After swapping the VGA-DVI adaptor (which works perfectly on another machine), Windows can now see the monitor. The nVidia panel sees the model and native resolution, but I get a constant 'No Signal' error. Switching to the other Displayport makes no difference. I suspect that the card is seeing a DVI connection plugged into it (nVididaCP shows the monitor as having a DVI connection), and it only sending out a digital signal because of this. Does anyone know of a solution (other than trying to get a Displayport-VGA adaptor), or of a way to force the card to see it as VGA? Thanks, ~Dentrasi

• How to multiseat with HW 3d accel on CentOS 6.3 Final?

  - by user35070

  I would like to setup a multiseat configuration on CentOS 6.3 (two video cards, two keyboards, two mice, two monitors) and have hardware accelerated 3D on both monitors. 3D HW acceleration rules out Xephyr. I saw somewhere that recent versions of GDM (3.3 and newer?) don't support multiseat, so do I have to install KDM to make this work? If I just create a duplicate section with new device identifiers in my xorg.conf file, will this 'just work'? Using different ports on the same video card and separate keyboards, mice, and displays, the result was a desktop which spanned both monitors with both keyboards and mice acting as the same input in the GUI. I will power down and put in the new video card and report on the results soon. Both video cards are nvidia. UPDATE after putting in another NVIDIA video card, default behavior (before changing xorg.conf) is that one screen works normally, and both mice and keyboards are connected to it. Changing xorg.conf and the display manager to KDM and following the directions here https://help.ubuntu.com/community/MultiseatX#Ubuntu_10.04_.28Lucid.29 , I have 2 mirrored screens connected to separate video cards, DRI enabled, and 2 mice both connected to the same pointer. Keyboards don't do anything, however, I probably just need to fix a setting in xorg.conf I would still like to get multiseat functionality, eg. separate screens with separate input devices I have verified that the separate X processes are running (see page above) using 'ps aux | grepX [01]'

• Weird connectivity issue wtih USB Wifi stick.

  - by Carlos Nunez

  Hi, all! I'm not sure if this is the appropriate place to throw this question out there, but I'll give it a shot. I'm setting up two PCs, and I've been having massive troubles getting a USB wireless dongle working. I have two Sony VAIOs (Windows XP, SP2) that I found second-hand, and since they will be in a location too far to connect by Ethernet (no, can't do patch panels here :p), I need to connect them by wireless. Easiest and cheapest way to do that at the moment is by using two USB wireless sticks that I've had for a while, but never used. One of the computers is using a SMC-manufactured card, whereas the other is using a Belkin F5D7050. The box with the SMC card can see and authenticate with my router just fine, and has no problem obtaining a DHCP lease. The box with the Belkin, on the other hand, isn't so lucky. While it can see my router and associate with it, it will not obtain a DHCP-issued address. Worse, when I assign a static IP address to the NIC, it can ping the entire network and access the internet (meaning it can authenticate with the router), but no computer can ping to it UNLESS that computer pinged the computer that's pinging it first. Confused? Well, so am I. Has anyone had this issue before? Is this just a sign of a bad card? (For the moment, I have it connected by Ethernet, as I haven't moved it yet. However, this will be a problem when I set it up in its new home later.) Thanks! -Carlos Nunez

• Problem importing pictures from a digital camera with Windows 7

  - by snark

  Hi, Since I'm using Windows 7 (Beta, then RC, now RTM), I have issues when I download pictures from my digital cameras. It happens with my 2 cameras: a Canon Powershot S2 IS and a Canon Ixus 80 IS. When I plug a camera (any of them) to a USB port and switch it on in Play mode, the Autoplay function of Windows 7 starts with this screen: I select "Import pictures and videos" to call the native Windows 7 tool. It searches a bit for pictures to download from the camera and starts the transfer. However, during the transfer, I often get errors like this one: If I use "Try again", it works fine the second time and the picture is retrieved correctly. It's very annoying when it happens 20 or 30 times in a 500-picture download. I cannot leave it running standalone, as I have to watch for the errors and click on "Try again". Any idea what is causing these errors? I tried changing the USB port (normally the cameras are connected via a USB hub but it happens also when I connect them directly to a MB USB port) and the USB cable, but no success. I also checked the SD card by connecting them with a card reader and running a ChkDsk on them but it found no errors on the cards. Update: No problem when I copy the pictures manually with the Windows Explorer. And no problem either when I access the card with a reader. The builtin import tool of Windows is convenient as it sorts the pictures automatically by date (1 folder per day). And this is the way I sort my pictures

• Dual Monitor Setup with Ati Radeon Hd 5700 results in unusabledesktop win7

  - by NorthPole

  I have an ATI Radeon HD 5700 card which i've been using under fully updated windows 7 with its latest drivers. My monitor is a 2004 NEC LCD1703M which despite being pretty old runs fine. A friend gave me an IIYAMA ProLite E1900WS monitor (2009 or 20010 ). Both monitors are vga only. I've been using a DLDVI to VGA adapter to connect my old monitor and tested the same adapter to the new monitor and it worked fine. So I bought an HDMI to vga adapter with the purpose of having a dual monitor setup. But when both screens are connected to the card the following problem occurs: The monitor connected to the hdmi port cycles between sleep and a black screen while the other shows the operating system for about two seconds before getting black for another two seconds. I can "use" the computer (move the mouse,click,type e.t.c.) while this happens but its not something pleasant. I tried reinstalling the driver, booting with both screens connected (in which case the powerup messages and the bios are mirrored in both screens until I get to the login screen where everything falls apart) Funny thing is, everything works if I disconnect the ATI graphics card and use the onboard intel one. So, any suggestions as to what might be the problem and how I can fix it?

• LSI 9260-8i w/ 6 256gb SSDs - RAID 5, 6, 10, or bad idea overall?

  - by Michael Pearson

  We're provisioning a new production server for our reasonably busy website. Our choice of host have available a 6 drive configuration with a LSI 9260-8i card. My initial thought was to fill all six bays with SSDs (Intel 520 256gb) and set them up in RAID. Good, bad, or terrible idea? Can the card handle it? Should we be using RAID 5, 6 or 10? This would be the first time the provider have filled all six slots for this rackmount with SSDs, so they're a bit hesitant. I'm wondering if somebody else with this card has done something similar in a production environment. We do about 43gb of writes per day and currently use about 300gb of storage. The server acts as webserver, database, and image store for approx 1 million files. The plan is to underprovision the SSDs by approximately 10% to 20% to increase their overall lifespan & performance. The fallback option is 2x480gb SSDs in RAID 1 and another 2x1TB HDDs in RAID 1. The motivation behind this is that the server rental cost difference between 2xSSDs and 6xSSDs is minimal (compared to the overall cost of the rental). We do not have any special high-IOPs requirements. However, if the configuration is known to work, I don't see a good reason to not use it and not have to worry about having separate 'fast and small' and 'slow and large' disks.

• Diverting sound output of MCE to SPDIF

  - by Saxtus

  I have an ASUS SupremeFX II audio card (which in fact is an onboard audio riser slot) with the default drivers that are pre-installed by Windows 7 x64 for this card. I am able to manually switch between analog output and SPDIF output by the means of control panel (or external utilities like STADS), a change that affects all applications. The problem is that by doing that every time I am about to launch Windows Media Center, except that it's not that elegant, also makes all other Windows application's sounds to pass through SPDIF too, bypassing analog output completely, blending with what I am watching at Windows Media Center. Is there a way to make SPDIF as the default playback device for Windows Media Center? I know other programs that have a setting like that (foobar2000 for example) working like charm, allowing me to even have different outputs working at the same time (tested with my current card successfully). But when comes to Windows Media Center... it just use what the default playback device is all the time. The only setting that I know of, is under: Settings General Windows Media Center Setup Set Up Your Speakers and what it does is to just change the default playback device for entire system. Please help!

• What speed are Wi-Fi management and control frames sent at?

  - by Bryce Thomas

  There are a bunch of different 802.11 Wi-Fi standards, e.g. 802.11a, 802.11b, 802.11g, 802.11n etc. that all support different speeds. Wi-Fi frames are generally categorised as one of the following: Data frames - carry the actual application data Control frames - coordinate when its safe to send/reduce collisions Management frames - handle connection discovery/setup/tear down (e.g. AP discovery, association, disassociation) My question is about whether all these frames, and specifically management frames, are transmitted at the fastest supported speed available, or whether certain classes of frames are transmitted at some lowest common denominator speed. I have noticed that when I put an 802.11b/g only device into monitor mode and capture traffic over the air, I still see management frames (e.g. association/disassociation) being transmitted between my phone and AP which are both 802.11n, even though 802.11n has a higher transfer rate. So I am imagining one of two possibilities: My 802.11n phone/AP had to negotiate a slower speed for some reason and that's why I can see their frames on my 802.11b/g monitoring device. Management frames (and perhaps control frames also?) are sent at a lower speed, and it's only data frames that are transmitted faster with newer 802.11 standards. The reason I would like to know which one of these two possibilities (or perhaps a third possibility) is the case is that I want to capture management frames, and need to know whether using an 802.11b/g card is going to lead to me missing some frames sent at higher speeds than the monitoring card can observe. If management frames are indeed sent at a slower rate, then it's all good. If I just happen to be seeing the management frames because my phone/AP have negotiated a slower rate though, then I need to reconsider what card I use for packet capture.

• ATI HDMI Audio disappears in Windows 7 when a TV is connected

  - by jsalonen

  So far I have unsuccessfully googled for HOURS with no luck fixing this very annoying problem. The settings is the following: I have PC running Windows 7 RC (64-bit) Video card is a ATI Radeon 4850 series card (Sapphire HD 4850 512MB to be exact) The video card has HDMI out with built-in audio chip I have an HDMI cable connecting the PC to a TV (Sony Bravia series) The problem is that when I connect the HDMI cable to the TV, the ATI HDMI Sound output device disappears completely from the list of playback devices in Windows. As a workaround I can restore the audio by re-installing the HDMI audio driver. However, when I disconnect the TV the driver disappears again. So basically, every time I want to watch stuff on my TV, I have to reinstall audio driver, which of course is VERY annoying. EDIT: I have figured out that I do not need to re-istall the HDMI audio driver to restore sound; I only need to reboot my computer with the HDMI cable plugged in to restore the audio driver. This suggests that the problem has something to do with information passed from TV to computer, which makes my HDMI Audio driver disappear. Are there any other, more elegant workarounds for this problem? All help is much appreciated!

• SPDIF passthrough not working in Windows 7

  - by adriangrigore

  Hi, I'm running Windows 7 on a computer with an Audigy Platinum eX sound card connected to a surround receiver via optical cabling. Sound works fine when listening to non-surround audio sources, such as windows sounds or MP3. However, when I view a DVD in Media Center and the SPDIF passthrough kicks in, I can only hear an awful noise instead of the movie soundtrack. Also, the receiver does not show the Dolby Digital or DTS symbol, but stays at Dolby Prologic, so it seems it doesn't identify the sound encoding properly. I could switch off SPDIF passthrough and use the sound card's decoder instead, but that's not an option for me since it would create more problems with regular MP3 playback via additional Stereo Receiver which is also connected to the same sound card. I've tried both the default Audigy drivers that come with Windows 7 and the latest drivers from the Soundblaster website, but the problem remains unchanged. Also, I have ensured that the receiver's Dolby Digital decoder is not broken by successfully connecting it to my PS3 to view a Dolby Digital DVD. Besides, SPDIF passthrough was working fine in Vista before I upgraded to Windows 7. Is there anything else I could try?

• Slow File Copy observed copying 40GB files across network to iSCSI device

  - by Rick

  Here's a curious ones for the gurus: Setup: Source Machine: Windows Server 2003 R2 machine with local hard drive. VHD file of 40GB. 1 x 1Gbps network card, Cat6 cable, switch. Target Machine: Windows Server 2008 R2 machine with iSCSI connection to iSCSI target on separate machine (1TB, RAID5). 1 x 1Gbps network card, Cat6 cable, connected to same switch as for Source Machine. Second 1Gbps network card, Cat6 cable, connected via isolated switch to the iSCSI target. Switches are Netgear JGS524 model (web managed). If I copy from the Win2003R2 machine to Win2008R2 machine local drive I get 40GB in 45 minutes, 36 seconds. If I copy from the Win2008R2 machine to the iSCSI target (local drive to iSCSI target) I get 40GB in 37 minutes 56 seconds. If I copy from the Win2003R2 machine to the iSCSI target via the Win2008R2 machine I get 40GB in 3 hours, 50 minutes, 24 seconds. All copies were done via the following command issued on the Win2008R2 box: XCOPY <source> <target> /J XCOPY /J - Copies using unbuffered I/O. Recommended for very large files. So, what's the bit I'm missing here? Why does a back-to-back copy take in total 1 hour, 23 minutes, 32 seconds when a "straight through" copy take almost 3 times as long? Switches show no errors, network hovers around the 3% utilisation mark for the duration of the copy (whereas the "back-to-back" copies are around the 25% utilisation mark). What have I missed?

• Problem with setting up raid5 on Freenas, Please help.

  - by Benjy23

  Hey Guys, I've been running Freenas for awhile now. Hardware is 1.8celeron Ram 1GB Sata Card is Via - not sure the model.... its 2 ports and I have 6 x 1.5TB HDs All ran ok while running on 1.5TB, no raid. I'm now trying to create a raid5 with my 6 hds. Software raid... is it normal for it to take roughly up to 2 weeks just to build the raid? Sorry, I'm very new to implementing raid and googling doesn't tell much other than it takes a long time. Also the Raid building process seems to fail many times... going to degraded. I suspect its cos 4 of my HDs are connected to my motherboard and the other 2 are connected to my sata card...what's your take? I'm considering 2 options now... either get a 8 port sata card and attach all the HDs to it. Or get a raid controller 8 portcard which is probably gonna be more pricey... also how do you access hardware raid through Freenas? I like how Freenas emails you should your harddrive fails so can this be done as well with hardware raid? Thanks in advance guys.

• Ubuntu 10.04 freezing and Ctrl + Alt + Backspace does nothing but music keeps playing

  - by Bryce Thomas

  I'm having intermittent problems where the screen will freeze in Ubuntu. I've tried using Ctrl + Alt + Backspace to restart the X-server, though this does nothing. When the freeze occurs, there's a small square of black dashes around the mouse pointer - maybe 1 inch in size. These dashes look a lot like a 2d barcode. The rest of the screen looks normal, but I can't move the mouse and none of the keyboard shortcuts work to do anything. However, music that I begin playing before the freeze continues to play, which seems to indicate it hasn't stalled up completely. I've noticed a similar freezing problem when I'm using Windows 7. That is, I see the same barcode like dashes around the mouse pointer when it freezes up. So I'm guessing it's either a driver or hardware problem. I thought if it was a hardware problem though, the whole computer might stop working (i.e. music would stop playing)? The video card I am using is an Nvidia, and I believe it's in the 7600 range. In Ubuntu I have the drivers for the card set to the latest available (proprietary). Ideally I'd like to be able to continue using the proprietary drivers. Is there any known issues with the drivers for this model graphics card, or has anyone experienced the same problem and knows how to fix it?

• How CPU communicates with HW

  - by b-gen-jack-o-neill

  Good day. I am new here, but I could not find answer to my question using google, so I help I do not violate any rules. So, basically, all I want to ask is, how CPU comminucates with other HW, such as printers, Graphic card, sound card, LAN card etc. I know, that for basic system I/O, you can use BIOS interrupts. INT 10h I believe is for display output. But, what I would like to know is, what actually happens when you execute instruction int 10h. From desription of int instruction, it should jump to routine, which is stored on adress pointed by adress stored in iterrupt table. But how does this routine get into the RAM? Does BIOS save that routines to the RAM? And what actually that routine does? I mean, CPU can only acess RAM, right? So how can now acess some other HW? Is there some special instrucion for it? Or is CPU somehow connected to BIOS, and than BIOS actually does the work? And the last thing, does even OS like Windows or GNU/Linux use BIOS interrupts, or can OS acess HW directly? Thanks.

When awakened after a hibernation it says: The system could not be restarted from its previous location because the restoration image is corrupt. Delete restoration data & proceed to system boot? Double reboot (inconsistent): Monitor must be plugged into the graphics card. Screen resolution - 1024x768 Odd icon shows in system tray whose tooltip says "Intel Graphics" For a while my morning ritual was to boot, wait, reboot using (alt+ctrl+del - ctrl+u - R), wait. Keeping the monitor plugged into the graphics card. But aside for the inefficiency of this method, I sometimes want to standby and can't. On the other hand, the computer is unusable when set to 800x600. Please help, anyone?

• Triple monitor setting in Linux with USB-HDMI adapter

  - by Oscar Carballal

  I'm trying to set up a triple monitor desktop at my office using Fedora 17, but it seems impossible, let me explain the setting: Laptop ASUS K53SD with 2 graphic cards, Intel and nVidia (Screen controled by Intel card) 24" Full HD monitor connected to the HDMI output (controlled by Intel card) 23" Full HD monitor connected to an USB-HDMI adapter (via framebuffer in /dev/fb2, apparently) VGA output (not used) controlled by nVidia card First of all, the USB-HDMI adapter works perfectly, it gives me a green screen (which means the communication is OK) and I can make it work if I set up a single monitor setting via framebuffer in Xorg. Here I leave the page where I got the instructions: http://plugable.com/2011/12/23/usb-graphics-and-linux Now I'm trying to set up the the two main monitors (laptop and 24") with the intel driver and the 23" with the framebuffer, but the most succesful configuration I get is the two main monitors working and the third disconnected. Do you have any idea what can I do to make this work?

• MacBook Pro and Backtrack 5R1 Configuration

  - by user119346

  I have a Macbook pro Quad core (2.2/8gb ram/750gb hdd). I have went through tons of forums on the Internet, but none of them seemed to be updated for the current Backtrack 5R1, or the question of getting it to correctly work on the MBP. Can anyone help? I don’t have a USB Dongle, and I want to be able to use the internal airport extreme wireless of the MBP to use BT 5R1. I have downloaded Backtrack 5R1 onto VMWare Fusion, and got it up and running, but to no avail. It keeps recognizing my card as a Ethernet connection. Kismac wont recognize the card either. So what I am asking for is this: The proper “download method.” for Backtrack 5R1 to my MacBook Pro. (YES I AM WILLING TO RE-DOWNLOAD BT 5R1). The Complete process from start to finish, UP TO DATE, from someone who has done this using an MBP Running Lion OSX. The proper tweaks, settings, or commands to get my airport extreme wireless card to work (it is BROADCOM 4331 I think). The wireless connection I need to use the tools on both Backtrack 5R1 and Kismac. I mainly need to test WEP cracking on my network for security. The difference between running BT 5R1 on VMWARE Fusion and running from downloading it directly to the MBP, if there is, How to download it directly to the MBP?

• Windows Explorer Hangs on Right-Click

  - by Bryan

  I am not sure if this is the right site to post this one as I typically post coding questions on stackoverflow. But I'll ask anyways and hopefully someone can move it if it's incorrect. Currently I have a customer built PC, utilizing an Intel i7 chip, 1300WATT PSU, 8Gigs of RAM, and two video cards. Originally I had the one video card (NVIDIA) that used the PSU and had two DVI output. After purchasing a third monitor I installed another ATI) graphics card not needed any PSU connectors. After installing and restarting, I noticed that when I right-click on my desktop, or through Windows Explorer it will hang, freeze then restarted. Sometimes after Windows Explorer restarts the problem dissipates. I checked to make sure everything was connected properly and it was. I repaired the ATI Catalyst Control Center to see if that had an issue, and I checked to see if either video card required updated drivers. Nothing worked. I tried restarting my PC and that didn't work. I tried using ShellXView (I forgot what it's actually called) and tried closed processes but that didn't work. Does anyone have any idea what could have caused this orpossible solutions I should try?< Thanks in advance.

• VMWare ESXi 5 - Expanded RAID 5 array - cannot access datastore

  - by Dayton Brown

  I'm using VMWare ESXi 5 and had a 2 TB RAID 5 setup on an HP DL360 with a P400i RAID card. I added two more 1 TB drives and using the SmartStart ACU, added the drives and expanded the logical disk. Now after booting back to ESXi, the server boots, but lists no available persistent storage. I've rescanned multiple times to no avail: the Datastore doesn't show up. I booted to GParted and the 1.8TB partition shows up, but it shows as unknown. Anyone have any good ideas? EDIT: Final Solution So after much gnashing of teeth, it was fairly simple to solve. I purchased an eSata 2 TB external drive and a PCI eSata card for my server. I then used Clonezilla to image the current partitions to my new external drive. You have to check "don't check drive sizes" in advanced mode, otherwise it will yell at you for have a smaller drive. For some reason my PCI card wouldn't boot on my HP server, so I hooked the drive up to another desktop I had, booted to VMWare, and copied the vmdk's to another drive. I'm going to blow out the RAID config and then create 1.5TB logical drives.
