• I keep losing wireless connection

  - by posfan12

  I have a WRT54GL v1.1 wireless router and a WUSB54G v4 wireless adapter, both made by Linksys. The router is in the living room by the TV and the my computer is in the bedroom. My ISP is Brighthouse. Operating System Microsoft Windows 7 Home Premium 64-bit SP1 CPU Intel Core 2 Duo E6600 @ 2.40GHz 36 °C Conroe 65nm Technology RAM 3.00GB Single-Channel DDR2 @ 333MHz (5-4-4-14) Motherboard eMachines EMCP73VT-PM (CPU 1) 26 °C Graphics ASUS VS247 (1920x1080@60Hz) 767MB GeForce GTX 460 (nVidia) 43 °C Hard Drives 466GB Seagate ST350041 8AS SCSI Disk Device (SATA) 35 °C Optical Drives HL-DT-ST DVDRAM GH41N SCSI CdRom Device Audio High Definition Audio Device The problem is that my Internet connection will work fine for 15 minutes or so. Then the data will just stop flowing. Windows says I am still connected, and the systray icon still shows five bars. But Comodo Firewall will stop showing up and down traffic, and another of my systray applications complains about a lack of connection. What I usually do is either disconnect from the network manually, or unplug and re-plug the USB adapter. At which point the connection will work properly for another 15 minutes. I've tried unplugging my router for 30 seconds and letting it reboot. I've also tried looking for a newer driver for my adapter but I seem to have the latest version 3.1.3.0. This is a recent problem starting about a week ago. For the previous several months things were working just fine. I haven't made any changes to my system that I am aware of. The only thing I did was open my case to blow the dust out of it, then put everything back together. How do I fix this issue?

• Reinserted a RAID disk. Defined as foreign. Is import or clear the correct choice?

  - by Petrus

  I have re-inserted a RAID disk, on a DELL server with Windows Server 2008. The drive-status indicator was changing between a green and amber light, and the monitor gave the following message: There are offline or missing virtual drives with preserved cache. Please check the cables and ensure that all drives are present. Press any key to enter the configuration utility. I pressed a key and the PERC 6/I Integrated BIOS Configuration Utility showed that the RAID Status for that disk was Offline. After reinsertion of the disk the monitor is giving the following message: Foreign configuration(s) found on adapter. Press any key to continue or ‘C’ load the configuration utility, or press ‘F’ to import foreign configuration(s) and continue. After checking around on the net I am uncertain if I should choose import or clear. I cannot find out if an import means importing information from the array/system to the now foreign disk or the other way, i.e. importing information from the foreign disk to the array/system that was actually working fine. Also; if clear is a necessary thing to do ahead of a rebuild of that disk, or if clear means to clear the system to somehow make it ready to import the information from the foreign disk to the array/system, which is not what I want. I imagine that making the wrong choice here might be fatal. Please help clearing this out by telling what to choose and why.

• How to eliminate overscan on Ubuntu HTPC

  - by Norman Ramsey

  I'm using an Ubuntu box with Nvidia graphics card as an HTPC. My HDTV is a Sony Bravia KDS-R50XBR1; this is a rear-projection unit with many inputs. I am using the HDMI input. I'm using the proprietary Nvidia drivers and they recognize the 1080x1920 resolution just fine. The display is a little fuzzy but at 50 inches it's perfect for movies. My problem is that the TV has three overscan settings, and none of them reduces overscan to zero. When I was using dual-screen this was fine, but I'm moving to where the TV is my only screen, and the Gnome panels are not visible because of the overscan. I'd like to figure out how to eliminate the overscan, without trying to scale my 1080p content down to 920p or something ridiculous like that. Ideally there would be some scurvy trick, perhaps involving the TV service menu, to get rid of the overscan on the TV side. Or I could move the Gnome panels, but I still would be missing the edges of my movies. Suggestions most welcome.

• Ubuntu 13.10 on Acer V5-472 with HD 4000

  - by Hyperboreus

  I have an Acer V5-472 with intel HD4000 graphics chipset and a built-in 1366*768 display. I have installed ubuntu 13.10 amd64 in legacy boot mode with an external monitor. Installation showed no problems, I can boot from HDD and log into my system. The internal display doesn't work and I have to use an external monitor. I have tried the following (found in other threads) to no avail: Setting grub option "acpi_backlight=vendor" or "acpi_osi=Linux" or both. Installing the intel HD drivers for Linux from their homepage. Running in circles, screaming and shouting. The internal display lights up (I can change the brightness with Fn-Left and Fn-Right) but that's all. When I boot, I get a purple splash screen and from then only the external monitor works. I read somewhere that this might be a problem with kernel 3.11? Has anybody ubuntu running on an Acer V5-472? Should I change ubuntu version or use 32-bit instead? In general, how can I get the internal display to work? Edit: The settings-display dialogue shows the internal display correctly with supported resolution of 1366.

• Apple video adapters: Mini-DVI to DVI + DVI to video?

  - by Ken

  I have: a Macbook (which has Mini-DVI output) an Apple Mini-DVI to DVI adapter (so I can hook up my Macbook to my DVI LCD) a Mac mini (which has DVI output) I see that I can get a DVI-to-Video (s-video and composite) adapter from Apple that will let me hook up my Mac mini to my TV set (which has only component, s-video, and composite -- nothing digital). So far so good. Question: Will that same adapter also let me hook my Macbook to my TV? That is, can I hook Macbook - Mini-DVI to DVI - DVI to video - TV set, and see picture? I know there are digital/analog/integrated variants of DVI, and it's not at all clear to me what pins these things have and what signals they're sending. One website I found suggested that it would work, and another suggested that it wouldn't even physically connect. So I'm looking for, ideally, someone who's actually tried it, or has these adapters sitting around to try. I know I can buy 2 adapters (Mini-DVI to Video, and DVI to Video) to do this, but at $20 a pop I'll avoid that if at all possible.

• How do I troubleshoot a slow hard drive?

  - by Bruce Connor

  My computer is suffering of slow-downs and I'm not surprised (it's around 6 years old). Here's what I've verified: They are not very frequent (only a couple of times a day). When they happen a single application will hang for 10-60 seconds, while the rest don't hang but also get slow. Even as it is happening, the CPU usage stays low. It happens to applications (such as text editor, firefox, skype). It never happens to some applications (such as games) which I use for hours under heavy CPU load. Also of note: The Graphics card and PSU are new (around a year). Though I have a decent amount of software installed right now, this was happening even right after I reinstalled Windows. This HDD has been through many partinioning schemes, and a few heavy operations (such as moving around 200GB of data). Because of the above, I am already 70% sure the problem is with the hard drive. Before I replace it, however, I want to rule out other less likely possibilities (such as RAM, software, or PSU). I don't have the money to replace the entire box right now, but I can easily replace one of the components. I've read several questions (such as this one) which give general guidance on troubleshooting an unknown issue, that is not what I'm looking for here. My main question is: What tests or benchmarks can I run to verify I have a problematic hard drive? I don't need to solve this problem, I am content with just making sure it's the hard drive. I could borrow a newer hard drive from a friend and see if it gets better. A positive result would rule out all other components, but it wouldn't rule out a software issue (since this new hard drive won't have any of the software I use daily). Running on Windows/Linux.

• SYS-5016T-MTFB will not POST without manual assistance (Motherboard: X8STi-F)

  - by Dan

  I have a Supermicro 5016T-MTFB 1U server which I am in the process of setting up, but it has a really strange problem. When the system is powered on it will not POST until I press the reset button a few times, followed by pressing the delete key on the keyboard to "wake it up". If I power it on and do nothing, the fans spin up but nothing else happens at all. After pressing the reset button once, the red "overheat" light comes on and blinks which is supposed to indicate a fan failure - but all the fans are working. Pressing reset again usually stops the blinking, and the system starts the normal POST routine but it will not actually get to the bios screen unless I press delete. If I don't press delete, it just continues to hang. After pressing delete it will take me into the bios setup screen, if I exit without saving changes I can boot the system normally. I was able to successfully install Linux with no trouble...but upon rebooting the same problem happened again. This board has integrated IPMI which I thought was the problem, so I disabled it via the jumper on the board. Did not help. Each time this system powers on, it goes on for a second, then turns off again for another second, then turns back on again. I don't know why it does that. Here is what I put in the system: 1 x Xeon E5630 (Nehalem) 80W TDP (it's not overheating, CPU temps stay under 40 degrees C) 2 x Kingston 2GB x 3 DDR3-1066 Memory ECC, unbuffered, unregistered (kvr1066d3e7sk3/6g) 1 x Intel X25-M 160 GB 2 x Western Digital RE3 1TB

• Configure Windows firewall to prevent an application from listening on a specific port

  - by U-D13

  The issue: there are many applications struggling to listen on port 80 (Skype, Teamviewer et al.), and to many of them that even is not essential (in the sense that you can have a httpd running and blocking the http port, and the other application won't even squeak about being unable to open the port). What makes things worse, some of the apps are... Well, I suppose, that it's okay that the mentally impaired are being integrated in the society by giving them a job to do, but... Programming requires some intellectual effort, in my humble opinion... What I mean is that there is no way to configure the app not to use specific ports (that's what you get for using proprietary software) - you can either add it to windows firewall exceptions (and succumb to undesired port opening behavior) or not (and risk losing most - if not all - of the functionality). Technically, it is not impossible for the firewall to deny an application opening an incoming port even if the application is in the exception list. And if this functionality is built into the Windows firewall somewhere, there should be a way to activate it. So, what I want to know is: whether there exists such an option, and if it does how to activate it.

• My EliteBook is not auto picking 1080p for external monitor, poor display on forcing

  - by Griever

  I'm connecting my Samsung LED S22A300B to my HP EliteBook 6930p through VGA out. Laptop has Intel 4500MHD video card. I have latest drivers installed for both card and monitor. Only 800x600 and 1024x768 are shown. A lot of other people get this problem when they use it with docking station as discussed here. But I am not using any docking station. The monitor works great with my desktop though. As advised on the aforementioned page, one of the things I tried was to force the resolution using Intel's "custom resolution" feature. I installed PowerStrip on my desktop and copied advanced timing values(front/back porch,sync width, etc.) from there and then used the same values while defining a custom resolution in my laptop's Intel graphics utility. As a result, I got the 1080p resolution but the display is poor. Text has some weird colored shadow and sometimes on images too. What should I do?

• How to let hard drive sleep in RAID1 configuration?

  - by Al Kepp

  Normally in Windows 7 a hard drive stops spinning when it is not used for a longer while. This can be configured in Windows and I use it on computers which are turned on 24/7 but not used much often. My problem is on a computer with Intel X79 chipset with an integrated RAID controller. There is Windows 7 installed on an SSD drive, and there is RAID1 array with two SATA HDD drives for data. Those SATA drives aren't used much so I'd like to let them sleep (i.e stop spinning). But they ignore settings in Windows. How to let them sleep when using RAID1? It seems to me that those drives are "unstoppable", they are spinning 24/7 even when they aren't used at all. Maybe they would behave normally if I used Windows-based software RAID, but I use hardware RAID controller. Is there a way to let them stop spinning and sleep after for example 3 or 5 hours of inactivity (i.e. the same way as they would behave in Windows without RAID)?

• CD-ROM Cant Be Accessed After Installing VMware Tools on VMware Server 2.0.2

  - by Optimal Solutions

  Using VMware Server 2.02, I set up a new VM (Windows XP Pro) applied all of the updates, added Windows addons from the install CD, etc... I got it to a stable point and up through that point I was able to access the CD-ROM drive (E: on my host). What I never did before was install "VMware Tools" and since it claims to give better mouse and video support, I gave it a shot. What it does is it places the install package in a virtual CD-ROM drive. I ran the install, no errors and it wants a reboot. I log back in after reboot and pop in the install CD for Microsoft Office 2003 and I receive the message "Please Insert A Disc Into Drive D:". Drive D: would be the next logical drive after the C: drive where I chose to install the OS. The message box sits there and if I click "Cancel", to return to Windows Explorer, the status bar seems to blink ever 1/2 second - as if its polling for a CD-ROM drive or something. No bangs or exclamations in the Device Manager for any hardware. I had taken a snapshot prior to the VMware Tools install and upon restoring it, the CD-ROM is back. I made copies of two other VMs, installed the VMware Tools on those VMs and both experienced the same issues: Windows 2003 Server and Windows 7 (32-bit). Has anyone seen this issue and know of a fix for this? It would be nice to have the better graphics and better mouse control AND use my CD-ROM drive as well! Thank you.

• Opera 10.5 RAM usage and Google Reader?

  - by David

  Hi all, Today I upgraded to Opera 10.5 from Google Chrome and I have two really important questions about it. 1) Is it normal for it to use SO MUCH RAM!!!!? Closing tabs doesn't help, but opening new ones add on to the usage. I can have just 4 tabs open and it goes up to the 300MB mark and I only have 1.5GB in my laptop, 596MB of it used by the graphics card so this really unacceptable. Is there a way to fix it? 2) Why does Google Reader feel so slow and unresponsive on it? It lags so bad when I just try scrolling through the page. I know Opera is known for being really smooth while scrolling through pages. There's also a white bar at the bottom of the page that I can get rid of. It blocks the "Next" and "Previous" buttons. The test between articles is also sort of intersecting each other and that just looks completely unattractive and that's something i'm not used with any web browser. I realize there's a built-in RSS reader, but it doesn't sync across multiple computers and is very late at updating. Here are my specs: Windows 7 Ultimate (x86), Intel Pentium M 1.86 GHz, 1.5GB RAM, ATI Mobility Radeon X600 (64MB dedicated, 596MB shared)

• Getting the most out of a Mac mini as a media center

  - by celebritarian

  Hello! I own an old Mac mini from 2006 (maybe early 2007). It's got an Intel Core Solo 32-bits CPU and 512 MB RAM. 160 GB HDD. The GPU is an integrated chip… Currently, my Mini is sitting under my LCD TV (720p). It's plugged in via a DVI to HDMI cable. It's currently running Leopard. And unfortunately, Snow Leopard can't be installed on a device with less than 1 GB of RAM… So, my Mac mini isn't exactly powerful. Also, it's slow and Mac OS X is not a pleasant experience on my Mini right now. It feels slow and heavy. I want to use my Mac mini as a media center/player. I want to be able to play video files in 720p (H.264, Matroska/MOV files). So basically, playing high-def videos is all I want to do with my Mini. What OS should I install? Stick to OS X? Optimize for video playback? Or should I install another OS — like Win XP, Ubuntu or any other Linux dist? Then, will my Mini be able to play 720p videos smoothly, even though the CPU and GPU aren't that powerful and with the limit of 512 MB of RAM? Appreciate all help. Thanks in advance!

• Best CPUs for speeding up compiling times of C++ w/ DistGCC

  - by Jay

  I'm putting together a distributed build farm with DistGCC to speed up our teams compile times and just looking for thoughts on which processors to use in the hosts. Are we going to get a noticeable decrease in time using 8 cores vs. 4-hyperthreaded cores? Big difference in time between i7 and Xeon? etc, etc. Just need advice from people who've put together kick-a build clusters. We've got a majority of the normal things to speed up builds in place (pre-compiled headers, ccache, local gigabit connections between them, tons of ram, etc) so please just give advice on the best processor to use. And money is a factor, but anythings doable if the performance increase is noticeable. Thanks. Jay EDIT: Although any advice IS welcome, please refrain from "Do this first" posts as we're not planning on skimping on things like SSD, maxed out RAM, etc. My personal system is a iMac Quad-core i5 with 8GB of RAM. When I build our project locally, my processor floats around 99-100% a majority of the time, which makes me assume it is a bottleneck, even if you made everything else faster. My ram on the other hand doesn't even get close to maxing out. It's also worth noting that I did research this, however every discussion I could find was primarily for gaming machines, which is obviously a different beast in usage. These machines won't even have monitors or anything but integrated graphics since they have one purpose: Build freakin fast. (hopefully)

• New XPC: No video, no ethernet link, but drive spins

  - by Mike Pennington

  I bought a Shuttle XPC SH67H3 with integrated video. I installed: An Intel i5 2450P 16GB DDR3 RAM A SATA hard drive from my old linux server that still is bootable I have both power connectors plugged into the motherboard. I realize that the Intel i5-2450P doesn't have video capabilities; however, the drive spins like it's doing something useful. It seems like I should get an ethernet link light when I fire this up. I plan to run this headless anyway, so it would be really nice if I could figure out how to run this without a video card at all. I know the IP address and login info for the linux install on the disk. I plugged in speakers, but get no bios beeps when I power it up. Shuttle's bios manual has nothing in there that indicates I should have problems in this configuration. My questions: Is there a reason that the missing video card would block usage of the ethernet port? Are there settings on the motherboard / bios I can change to get this working?

• How do photoshop slices and layer comps interact?

  - by Steve314

  I'm interested in using Photoshop (I have CS2) for some user interface design. I was hoping to be able to use slices and layer comps to mark out particular elements, and use Javascript scripting to export multiple graphics files and text descriptions (positions and sizes of slices mainly) that will be used by my program. My problem is that I've never used Photoshop for web design, or otherwise used slices, and I'm not confident that I understand how they interact with layer comps. This is what I believe (and hope) is correct... Manual slices aren't affected by layer comps in any way - they aren't saved as part of a layer comp. The same manual slices will be active irrespective of which layer comp is selected. Layer-based slices aren't directly affected by layer comps, but they are indirectly affected in that the layer comp saves details of layer position and style. Thus selecting a layer comp may move a layer and change its style, affecting the location and size of its layer-based slice, or may effectively disable the slice by hiding the layer. Automatic slices aren't directly affected by layer comps, but are indirectly affected due to changes to the layer-based slices. So, layer based slices (which are my main interest) may move, may change size (to accomodate a style such as a drop shadow), and may be effectively disabled by the layer being hidden. Other details (and all details of manual slices) will remain constant irrespective of which layer comp is active. Is that correct?

• Graphic Design in Outlook HTML Emails

  - by PhilPursglove

  At the moment we are creating artwork in Word and saving it as an HTML file. Opening up a new email, clicking insert on menuclicking ‘File’Selecting HTML file and choosing insert as text. The word document is then embedded into the email and we can create HTML links from there. The problem with this method is we are limited to what we can create visually in Word. The artwork just does not look professional enough and we find that sometimes the headers or footers do not appear or do not stay in their correct position. What I would like to do is to be able to start in Adobe InDesign (the graphics package we use). So far I have been able to create artwork in InDesign and create buttons and hyperlinks in InDesignExport it as a pdf, maintaining the hyperlinksSave as HTML documentOpen new emailInsert HTML file choosing insert as text. The problem with this method is that the images move about, the text is all different sizes, but on the plus side, the hyperlinks have been retained. So I am almost there, but not quite. Can anyone suggest what I need to do to get the design to display 'correctly' in Outlook.

• Ubuntu 12.04 froze during update, won't boot

  - by Cichol

  I've recently installed Ubuntu 12.04 on my laptop, and every time i tried to update it, it would freeze for a few seconds, and tell me that the updates could not be downloaded. After many, many tries I managed to get them downloaded, but then in the middle of installing them, it froze. Completely. No mouse movement, no blinking lights, no nothing. After a few hours of letting it sit there, I finally hit the power button to do a hard reset, and now when I select Ubuntu on the boot screen (Dual-boot with Windows 7), I get a blank purple screen, and then nothing. Another freeze. I've tried getting into the console, but no command I input has any visible effect. I have a ton of music stored on the partition it's in, so I'd really rather not have to reinstall. My specs, to the best of my knowledge: Clevo Corp model B7130 (Sager custom) CPU: Intel Core i5 @ 2.53gHz (4 CPUs) Graphics Card: Nvidia GeForce 425m 4096 MB RAM Drivers: Whatever comes with the download of 12.04. As a side-note, I installed Ubuntu via the Windows Installer program (wubi). Does that make a difference?

• Temporary boot problem after thunder storm - likely causes?

  - by alastairs

  The village where I live was sat under a thunder cloud for most of Friday, and we suffered a few power fluctuations (specifically, what seemed to be split-second outages). When I got back home from work, I found that my PCs had shut down during one of these outages. When I went to boot one of them back up, I couldn't get anything to display on screen, nor did the boot seem to complete correctly. I tried a number of things - unplugging different bits of hardware, swapping graphics adaptors, etc. - to no avail. I thought I was looking at a fried motherboard or CPU. Power seemed to be distributed correctly to the peripherals (the drives all appeared to be working) so I figured it couldn't be the PSU. Eventually I unplugged it from the mains and left it overnight (approx 12hrs unplugged). I tried it again this morning, and it booted up correctly. Woo-hoo! I have all my equipment protected by surge-protected power strips, so I don't think a spike caused these problems. Obviously it has something to do with the power fluctuations, and maybe the PSU in the problem machine got itself confused somehow. The questions are, for future reference and to help people with similar problems: What are the likely causes of the boot failure I experienced? Is a UPS a simple and cost-effective solution, or might other things help prevent this happening in future? What UPS can you recommend (my budget is limited)?

• Lenvo B450 won't boot on battery only?

  - by Mywiki Witwiki

  We bought a Lenovo B450 laptop almost a year ago. It comes with a NVIDIA GEFORCE with CUDA graphics and so the battery life is terrible. It will only last 1:30 hours max. We try to run it on battery as much as possible but because the battery life is short sometimes we can't notice that the battery is so low until the computer blacks out. Because of the short battery life, the laptop is always plugged on AC power. One night the computer froze. Because it was already late, I just reset the laptop my pressing the power button for 10 seconds. The laptop shut off but I did not bother restarting it. The next morning, the laptop won't turn on on battery only. It will only turn on on AC power. The computer instantly shuts down(improperly) once the adapter is removed. But the battery was at 100% then. Now it is slowly losing charge (currently at 74%). The battery indicator says, "Plugged in, not charging". I want to bring the laptop to school but I can't because it won't be portable at all. Just to summarize it all: 1) The laptop suffered some blackouts already. 2) The laptop was on AC power most of the time. 3) When the computer froze, it was reset (hard shutdown). 4) The laptop won't boot with battery only since then. 5) The laptop will shutdown instantly when AC adapter is removed. 6) The battery won't charge and is gradually losing charge. ======================= UPDATE ============================= We got the battery replaced. Unfortunately, it delivers only 2 hours max of power.

• PDF to HTML - batch converter - most reliable and accurate free AND paid for software?

  - by therobyouknow

  I'm look for either a free or paid-for (about 50$/40pounds) BATCH PDF to HTML converter to convert several PDF files at once. Needs to be able to handle vectored and bitmap images within the file, outputting both as jpegs referenced by the html pages. I've tried iorigsoft paid-for PDF to HTML - problems it seems to hang or just go idle, and the stuff it actually converts have broken links - the wrong name is used for constituent chapters as html. Also tried application from intrapdf.com but this crashes near the beginning of the conversion, consitently. Update: intrapdf works on my Windows XP machine but not on my Windows 7 machine. The only glitch is with the framed index contents html - the graphics in the page do not display in the page in the frame - but if you open the frame only in a new tab then you can see them. That might be a browser glitch in chrome only. This solution is good enough for me - given that I've already spent the money (I had spent before I asked) but I can't accept my own answer as this does not work on Windows 7. Looked at opensource tools but they look equally flakey or use old PDF versions. Need it on Windows 7 32bit home. Thoughts?

• I need help choosing between two configurations of the Dell Studio 14

  - by Adnan

  There are two configurations of the Dell Studio 14 (1458) which I'm looking at: Config 1: Core i7-720QM @ 1.6 GHz; ATI Mobility Radeon HD 5450 1GB; 4gb DDR3 RAM @ 1066 MHz; 500 GB SATA HDD @ 7200 RPM; Price: $999 Config 2: Core i5-430M; ATI Mobility Radeon HD 4530 512MB; 4GB DDR3 RAM @ 1066 MHz; 500 GV SATA HDD @ 7200 RPM; Price: $874 What I want to know is, would config 1 still be able to do decent gaming (maybe some Starcraft II), and is there a great performance difference between the i5 and i7 processors? Is the $130 extra worth it for the i7 and better graphics card? I do more than just basic computing. I plan on getting into web design (specifically using Photoshop and Dreamweaver), and I wish to do gaming. I know Conifg 1 is the better value, but I want to be sure that the $130 more is truly worth it. I dont have too much money and want to spend wisely as possible, yet I am a computer geek and plan on doing a lot more than the average user.
