• Connecting XRAID to Sunfire via LSI FC card - Drives not showing up

  - by Matthew Watson

  Hi, I've got a Sunfire T1000 machine ( Solaris 10 10/09 s10s_u8wos_08a SPARC ) with a LSI7404EP-LC fibre channel card in it. This is plugged into an XRAID. The system seems to have picked up the card > /usr/platform/`uname -i `/sbin/prtdiag IO Location Type Slot Path Name Model ----------- ----- ---- --------------------------------------------- ------------------------- --------- MB/PCIE0 PCIE 0 /pci@780/fibre-channel fibre-channel MB/PCIE0 PCIE 0 /pci@780/fibre-channel fibre-channel MB/NET0 PCIE MB /pci@7c0/pci@0/network@4 network-pci14e4,1668 MB/NET1 PCIE MB /pci@7c0/pci@0/network@4,1 network-pci14e4,1668 MB/NET2 PCIX MB /pci@7c0/pci@0/pci@8/network@1 network-pci108e,1648 MB/NET3 PCIX MB /pci@7c0/pci@0/pci@8/network@1,1 network-pci108e,1648 MB/PCIX PCIX MB /pci@7c0/pci@0/pci@8/scsi@2 scsi-pci1000,50 LSI,1064 However it doesn't seem to be able to see the xraid attached to it, lsiutil only reports the onboard SAS controller. > /usr/local/bin/lsiutil ~ LSI Logic MPT Configuration Utility, Version 1.62, January 14, 2009 1 MPT Port found Port Name Chip Vendor/Type/Rev MPT Rev Firmware Rev IOC 1. mpt0 LSI Logic SAS1064 A3 105 010a0000 0 Select a device: [1-1 or 0 to quit] I've tried adding the configuration to /kernal/drv/sd.conf and /kernal/drv/ssd.conf as per this thread, however format still cannot see any drives on the xraid.

• Network card very slow, only on Windows

  - by J Penguin

  This only happens to 1 of my machine, and only when booting into Windows 7. No matter what network card I put in, Windows would default its mode to 10Mbps full duplex. Transfer speed is approximately 1 MB/s. If I set it to 100Mbps, the transfer drops to 100-200K/s. If I set it to 1000Mbps, the connection is lost completely. I've tried swapping in different cards, both PCI-E and PCI. I'v etried update the windows, I've tried reinstalling the drivers... On this very same machine, if I boot into Fedora, it can use the card at its full capacity 1000Mbps transfering 80+ MB/s And all the cards work just fine when plugging into other machines on the same network. I'm very curious. What could be the reason for this? The only different software that this machine has is virtual box with a VPN emulator, but disabling that VPN doesn't seem to do anything. I would like to get this fixed, hopefully, without reinstalling windows _< Will that be possible?

• Network card/driver stops under heavy load

  - by Uwe Keim

  Since about approx. 2 month, I do have the following issue with my approx. 1 year old development machine (Windows 7, 64 bit): When doing network intensive operations, like e.g. executing some SQL script on a remote SQL server to select or update 1000 of records, the network card stops working. I.e. suddenly, No network connection is present anymore. No internet, no local connection, simply nothing. The only resolution so far I found is to disable my network card and then simply enable it back, like in the following screenshots: 1.) Click "Deactivate" 2.) Click "Activate" (German screenshots only, sorry) Now this is an acceptable solution to work around this issue, but I would love to have this fixed, since it suddenly stops me from working when I'm connected remotely via VPN/RDP on my machine (Win7 64bit). So my question is: Could you imagine a possible cause for this issue and give some hints how to hunt/resolve it? I could imagine that this is a driver issue, a hardware issue or even some kind of background software issue like a software firewall or a virus scanner.

• Driver denied access to PCI card

  - by Corin

  Alright, I asked this on StackOverflow (here) and they suggested trying ServerFault to get help on permissions. So here's the deal. We designed a custom PCI card and wrote the driver for it. It's been working for years without problems but now we encountered one particular installation were it doesn't work. The problem is that we cannot connect to the PCI to begin communication with it. We tried replacing the card and had the same problem. We had the motherboard replaced thinking the PCI slots were bad. That didn't help either. We tried the cards in a different computer and they all worked. So it seemed to be something specific to the computer. The Windows Device Manager indicates the device is working properly and seems to have all the correct driver info. We now have this troublesome computer back at the office for testing. With the help of some extra debug info in the driver we determined that we cannot connect because access is denied. Sounds like a permissions issue to me. I should note that we are logged into the system as a local administrator. So what configuration option in Windows can prevent access to a device?

• wild card redirects issue giving error this webpage has a redirect loop

  - by david

  In my website I changed or better word modified the directory name ""vehicles-cars"" to ""vehicles-cars-for-sale"" when i tried to redirect using wild card redirect my old directory name to new directory name in my web hosting cpanel account. every time when i open pages from that directory i am getting error code. This web-page has a redirect loop. The website is php. The problem is that that my lots of pages from old directory are indexed in googles and they are getting duplicate contents. If I redirect single page it works perfect but there are lots of pages so I need wild card redirect to redirect whole directory . I really need some advice what to do with this problem. Here is .htaccess file code for redirect thanks RewriteEngine on RewriteCond %{HTTP_HOST} ^example\.com$ [OR] RewriteCond %{HTTP_HOST} ^www\.example\.com$ RewriteRule ^vehicles\-cars\/?(.*)$ "http\:\/\/example\.com\/vehicles\-cars\-for\-sale\/$1" [R=301,L] i have other wilcard redirect of whole directory with same code and its working perfect here is the code in .htaccss file which is same as above and working perfect for this directory RewriteCond %{HTTP_HOST} ^adsbuz\.com$ [OR] RewriteCond %{HTTP_HOST} ^www\.adsbuz\.com$ RewriteRule ^autos\/?(.*)$ "http\:\/\/adsbuz\.com\/vehicles\-cars\-for\-sale\/$1" [R=301,L] so i dont understand whats wrong with the above code please i really need some expert advice thanks again

• Linux virtualization choices with graphic acceleration / video card support

  - by Urbn

  I am in the process of building a new desktop machine for work and fun. I am looking to run a undecided flavor of Linux (guessing Ubuntu) as my primary OS and several Windows installs with a Windows 7 install for .net development and gaming as virtualized environments. From my previous experiences with virtualization software in Linux I was never able to find an application that offered descent video card support / graphic acceleration etc. to be capable of playing any games within one of the virtualized environments. And since I will be investing quite a bit of money into this system for gaming I would naturally want to find the best option available to achieve this setup. So Onto my question: Is there any virtualization software available for Linux that has full video card support, graphic acceleration and capable of taking advantage of everything the video cards have to offer within the virtualized environments? Or am I stuck with running Windows 7 as my primary OS and using virtualization for Linux and the other OS's? Also I have no preference on open/closed source and price range would be up to $175.00 to support at least 3 virtualized environments.

• MacBook Pro (2007 - ATI-Card) Screen goes half black then shuts down the entire computer

  - by BluePerry

  Hey, when I'm starting my MBP I get about 10-60 seconds of the booting process before the screen goes half black (Its like applying a black to transparent gradient from the left side of the screen to the middle of the screen). After a 5 seconds the entire screen blacks out and the MBP shuts down. There have been issues with heat and some minor artifacts on the screen in the past but nothing serious as far as I know. Everything could be resolved by rebooting or letting the MBP cool down a bit. I would like to identify the problem now. There are 3 possibilities I can think of right now: My graphics card is defect and shuts down after a few seconds. (But if thats true, I find it kind of hard to explain the HALF black screen) My LCD-Panel is defect and sends back wrong signals so the system shuts down??? (I not sure about that) My fan or/and thermal sensors are defect and forcing the graphics card to shut down. Can anyone point if I'm right or if there yet another reason for this. I'd be thankful for any hint or tips. Cheers, Per

• Flash Backed Write Cache (FBWC) without capacitor pack

  - by Martyn

  I brought a HP Smart Array P410 controller and it is installed and working fine in a HP Prolient Microserver with 4 drives in two RAID 1 arrays. I didn’t realise however that it came without any cache so would only work by directly writing straight to the disk, and the performance was horrible. So I then brought the 512MB Flash Backed Write Cache (FBWC) memory module as I was under the impression that with FBWC I would not need a battery. I got this idea from a forum post. "What do you guys think of the choice between 'BBWC' (battery backed write cache) and 'FBWC' (flash backed write cache)? The flashed based ones use non-volitile memory so need no battery." After installing the cache module however the server pretty much won’t boot. The P410 has a flashing amber light on it, and from the manual that doesn’t sound good. I’ve managed to get to the on board BIOS once and even managed to get to boot to the HP Array Configuration Utility (ACU) CD once, but every other time the Server continuingly reboots once it get to the POST screen and reads ARRAY INITILIZING %%%. The one time I reached the ACU, it reported a problem with the Cache Module. To me, it seems like the cache module is faulty, however the supplier tells me “Do you have an FBWC battery pack, p/n 587324-001, because that is required for the cache to work. If you have it, please complete an RMA form and we'll send a replacement / credit.” Does this sound right to you? I’ve been ordering the parts from the US and I don’t want to spend $77 + $40 p&p on a battery, wait a week for the shipping to find the card is faulty, and I don’t want to send back a working card?

• I need a driver for my Cardbus USB 2.0 card

  - by Carl

  The picture and details of the card are here: http://www.ht-link.com/en/ProductView.asp?ID=106 The Windows drivers for this don't work right. I tried them on my previous laptop, and then installed the ones off their included CD. (Note that the systems requirements includes a CD-ROM drive...) I have a new laptop, and lost the CD. The website that lists the drivers is broken - the download links don't work. It is here: http://www.ht-link.com/en/DownView.asp?ID=10 I need the very first link - The Win XP drivers for the HT-112NEC. The company does not reply to my e-mails. I've tried searching Google for other sources for the driver (I didn't bother with those sites that want me to install driver detection software or create a log-in for their site). [Here's the problem I am getting using the drivers Windows XP SP3 installs: When I plug in my USB 2.0 hard-disk adapter, a USB Mass Storage Device entry is added in the Device Manager, but there is no entry under Disk Drives, and a drive letter is not assigned, so I can't access the driver. Like I said, this card didn't work without their special drivers on my other laptop, either.]

• Automatic switching of network card when vm is moved

  - by spock

  I have two hosts in a pool and I used to be able to move the vm around and they will start without any problem. But after I played around with some network setting, which I don't remember what, I started getting "This VM needs storage that cannot be seen from that server" message. As you can tell I am a beginner with Xenserver. Here is the very simple environment: 2 host servers with their own local hard disk and network card. One is a Pool master. Problem: Power off a vm and move vm from one server to another, or clone one vm to the other server. It used to be able to start up right away. Now, I need to delete one of the network that does not belong to the server, then it will start. Otherwise, the above error msg popup. The two networks (one for each network card in each host) are in the Networking tab of the vm, as well as in the host's networking tab. I googled but all I got to empty the DVD drive, which is not the problem here. Thanks in advance!

• ReadyBoost in Windows 7

  - by Robert Koritnik

  I've bought an SD card today for my phot frame, but when I inserted it into my notebook I saw I could use it for ReadyBoost. Some background I'm a .net developer, using VMs and developing web applications (and Sharepoint). I use an HP notebook machine with Core 2 Duo 2GHz + 4GB RAM + 320 7200 HD. I simultaneously run Visual Studio 2010 with some plugins SQL Server Firefox with at least 10 tabs Chrome with about 5 tabs IIS VM with Server 2008 machine Sharepoint and occasionally also Photoshop and some InDesign as well. So I don't let my machine have a break. :D Question If I buy myself some really fast SDHC card (like SanDisk 16GB Extreme 30MB/s - is there anything faster) and use it with my Windows 7 ReadyBoost, will I see any performance gain? Is it going to work something similar to Seagate's HybridDrive Momentus with 4GB of solid state drive? What could I actually expect if I do put this card into my machine? And what would be recommended size? Observations I guess redirecting page file to it would speed up the system. Some VM machines on it would probably run faster as well because they could run parallel to HD host system I guess. Am I right or wrong?

• Computer restarts without warning; code bcc116

  - by Robert C.

  Processor: Intel i5 4430 4-Core 4x3Ghz Motherboard: msi h87-g41 Graphics Card: Nvidia GTX760 Power supply: eps-750 cm RAM: 8GB I bought a new assembled gaming PC which worked fine for a few days. Then it started rebooting without warning. After it restarts windows 7 gives me an bbc 116 error code. Apparently it's something to do with my video card, either it overheating or wrong drivers. I've installed the latest driver from Nvidia for my graphics card. Since it's brand new it can't be dust, I'm running it with its lid open to see if the problem persists. I'm also running prime95 now to see if it tells me anything else. Using core temp it tells me that my CPU reaches up to 95° celsius with the blend stress test from prime95. Aaaand it just peaked to 100°. Of course it doesn't reach these temperatures at all while idle/gaming. I'm gonna let prime95 run for a night and to see what happens. Until then does anyone know what I should do next?

• Integrated Graphics went kaput, can I switch to dedicated graphics if I can't get into the BIOS

  - by Om Nom Nom

  I have an 8 year old computer (Pentium 4 1.6 GHz, 256 MB DDR RAM) which is not turning on (it beeps for 10 seconds and then goes off). Nothing appears on the screen, so I can't get into the BIOS. A computer repair person listened to the beeping pattern and told me that its because of the integrated graphics on the motherboard is defective. It's an ASUS P4S333-VM motherboard and the graphics solution is SiS 650. He tried putting in a PCI graphics card expecting that the computer will use that instead and ignore the integrated graphics, but apparently older computers don't switch automatically to the dedicated graphics card; it needs to be changed from the BIOS. But, I can't get inside the BIOS settings as I already said. I am told that the only option now is to replace the motherboard (which is not feasible since it's very old now). So, is there any way to make the computer use the PCI graphics card? IIRC, the motherboard also has an AGP port, but I think that it will also need to be selected from the BIOS?

• After update to Windows 8.1 brigthness isn't working (changing)

  - by Bibo

  I just update my Windows 8 to Windows 8.1 by Windows Store and I have some problems. My notebook is Acer Aspire Timelinex 3820TG and I know it's little old for Windows 8 but I install them and works fine (I updated my HDD to SSD). Now I just updated Windows and I have problem with changing brightness on my dedicated graphic card (Ati HD 5650). First I can changing brigthness with fn + keys but It just changing level in OS. No change in real. I tried reinstall drivers, install drivers for my card from Acer with compatibility to Windows 7 and without change. When I switch to integrated card changing brightness works. I think the problem is with drivers but I don't know how to get it working. Thanks for help Bonus question: I have another problem (but this one is not so important). Does anyone knows what msietxghh.exe is doing? Everytime when my system runs (after update) I get message that this program stops working but I just cancel and looks everything works fine.

• Recovering a damaged microSDHC

  - by djechelon

  I just bought from eBay a Kingston 32GB microSDHC that was advertised as defective. The seller said that there could be formatting problems or with transfer of large files. Unfortunately, when I got it, it was a total mess. My Nikon camera doesn't read it at all (OK, maybe it doesn't support 32GB) My Linux laptop doesn't mount it: can't read superblock The same laptop refuses to mkfs.msdos because it failed whilst writing reserved sector The same laptop, under Windows, doesn't read nor format the card HTC HD2 mounts the MMC, allows me to write via USB, but is unable to open the just written files OK, folks, now you would say I would have to go through Paypal complaint... that's not that easy. I consciously bought a half-price card that was known to show some defects, and Paypal complaints take time. Obviously, I can't accept somebody sold me a completely use-less computer decoration. So I'll keep it as last option. My question is Do you know a way, under either Linux or Windows, to thoroughly scan, test and possibly repair memory cards, even if I have to lose some percentage of space because of bad sectors? If I can keep at least half of the card intact it would certainly be fine. I used to do broken sector marking with hard disks in the past. I almost forgot: MONSTR:/home/djechelon # fsck /dev/mmcblk0p1 fsck from util-linux-ng 2.17.2 dosfsck 3.0.9, 31 Jan 2010, FAT32, LFN Read 512 bytes at 0:Input/output error

• Expanding to dual video cards

  - by Anthony Greco

  I know a lot of factors can go into play here, so I will list my current hardware and setup: MOBO: GIGABYTE GA-890FXA-UD5 [http://www.newegg.com/Product/Product.aspx?Item=N82E16813128441] Processor: AMD Phenom II X6 1090T Black Edition Thuban 3.2GHz [http://www.newegg.com/Product/Product.aspx?Item=N82E16819103849] Ram: G.SKILL Ripjaws Series 16GB (4 x 4GB) [https://secure.newegg.com/NewMyAccount/OrderHistory.aspx?RandomID=4933910872745320111128011418] Current video card: EVGA 01G-P3-1366-TR GeForce GTX 460 SE [http://www.newegg.com/Product/Product.aspx?Item=N82E16814130591] OS: Windows 7 Ultimate x64 Currently I can run 2 monitors just fine in my setup. However, I want to upgrade this to 4 monitors. My question is, what is the best way to do this? I remember in the past reading I need the same type of video card, however would any GeForce GTX work, or do i need that very specific model (EVGA 01G-P3-1366-TR GeForce GTX 460 SE)? Are there any issues I should be aware of before I order 2 new monitors and a video card? Are there video cards better setup for this? I know NVidia offers SLI, however I do not know if my mobo is compliant. My mobo also offers CrossFireX configuration, though from what it says only Radeon are compliant. Any suggestions / feedbacks on my best route with my current setup is appreciated. Even if you suggest buying 2 new identical video cards, as long as you can mention which and why that is better I really appreciate it. Note: I really do not do any gaming. I sometimes do some 3D work in Unity and very rarely in Maya. Besides that I mostly do all my computer work in Visual Studios and Photoshop. I however need the 2 extra monitors because I monitor sometimes 5 remote desktops at once and switching on only 2 is becoming a very big pain. Also seeing 3 side by side while I work on the 4th will be very helpful. Again, I appreciate any feedback, as I have googled a bunch and just want to make sure what I buy will work.

• How can I get Windows 7 to work with two Nvidia graphics cards with different drivers?

  - by Max

  This is similar to this question, but I am using more similar cards with Windows 7. I just purchased a Zotac Nvidia GeForce 7200 GS. I have a motherboard with two PCI Express x16 slots. There is already an MSI Nvidia GeForce 8800 GTS being used as the primary card, driving two LCD monitors. I would like the Zotac to output to a TV via DVI-out. Unfortunately, when Windows detects the Zotac and installs its drivers, or I manually install them, Windows stops being able to boot up. If I remove them and re-install the MSI 8800 drivers, I can boot again, but Windows can no longer see the Zotac 7200--it shows up as a yellow triangle in Device Manager. I've read conflicting reports about this. Some people claim that Windows 7 will support multiple heterogeneous graphics card drivers, as long as they are all using the same driver API ("WDDM?"). Others say that they have to be using the exact same driver, or it won't work. Others claim that you have to use the exact same card. which is it, exactly? I know I can run the MSI 8800 in SLI if I purchase another, but I don't need that kind of power--I just need HD-out to my television. I read somewhere that running two cards in SLI precludes you from using 100% of their output ports, so I'm not sure if that's an option. I suppose I could also run two MSI 8800's without SLI, but again, that's more power than I need (and more money than I'd like to spend). Also, I don't think this exact model is even manufactured anymore. Any ideas?

• ATI firepro will not detect a second DVI-D monitor

  - by John

  OK so weird issue here. I have previously been running 6 screens off of 3 of the older ATI firepro graphics cards but they had a problem with the heat sink getting too hot and warping the PCB resulting in total failure of the card, to replace my three dead cards I purchased a new-type ATI firepro with the newer heat sink design. I'm only using one at the moment to make sure they've fixed the problem before I waste more money on 2 more cards but this is where things start to get weird. The Firepro's only have one port on them, they connect to two monitors via a splitter cable going from the one port to two DVI connectors for the screens. When I plug two identical monitors in via their DVI inputs not matter what I do windows and Catalyst will only detect one screen. However if I use the VGA input on one of the screens with a VGA - DVI adaptor to plug it in to the card it works fine. This confuses me greatly. I'm currently using the ATI Firepro 2270 Graphics card with identical DELL U2311H screens. I can post the rest of the system spec as well if needed but I wouldn't have thought it would make much difference as it had no problem handling 6 screens before the graphics cards failed. Naturally both catalyst and ATI drivers are the most current version. ATI tech support has been absolutely zero help, they seemed to get stumped as soon as I verified that both screens were plugged in and connected properly. Anyone have any ideas?

• Hearing a clicking noise from soundcard all the time

  - by Mehrdad

  I have installed Fedora 17 on my laptop. A few days ago I updated my fedora (but not upgraded). I shut down my computer and since the next time I turned it on I am hearing a clicking noise all the time from speakers. Even when I plug my headphones in I hear the noise through the headphone. I surfed over the internet and found the following shell commands: su -c 'echo "options snd_hda_intel power_save=0" /etc/modprobe.d/snd_hda_intel.conf' su -c 'echo 0 /sys/module/snd_hda_intel/parameters/power_save' I tried them but they didn't work. Here is the part of "lspci" command related to my sound-card: 00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 03) I have to add that my sound-card is working and I can play some audio file, I mean I can hear the voice and noise simultaneously. But everything is OK in windows xp which is also installed on my laptop. Could it be related to the sound-card driver? If so, how can I revert it to the previous version?

• Windows 7 x64 support for Intel GMA 3650 (or GMA 3600)

  - by Loom

  I recently purchased an Intel D2700 MUD motherboard and I cannot find drivers for the Win7 x64 integrated graphics (Intel GMA 3650 aka PowerVR sgs545). The accompanying CD contains Win7 x32 version only. When I run it I got an error: This computer does not meet the minimum requirements for installing the software. I tried to use online utility Intel Driver Update Utility Graphics. I used Chrome, Firefox, Internet Explorer without success. First, UAC prompt appear, and then endlessly spinning progress-bar with text "Analyzing computer...". The text in UAC prompt is: Program file name: System Requirements Lab Verified publisher: Husdawg, LLC I downloaded this utility (intel_srldetect_4.5.5.0) and started it from my hard disk.

• What sound cards are there besides Creative's that offer benefits for gaming?

  - by Vilx-

  Many years (6? 7?) ago I bought an Audigy sound card to replace the onboard sound and was astonished at the improvement in games. It was a completely different sound, the whole experience became way more immersive. As the time has passed however the card has become old. The support for the latest Windows versions is declining and newer technologies have definitely been developed. So I was starting to wonder - what newer hardware exists? Sure, there is the Sound Blaster X-Fi, but that's quite expensive and I'm not entirely thrilled by past policies of Creative either (like the whole affair with Daniel_K). But are there any alternatives? EAX is a patent by Creative, so it's doubtful that any other manufacturer has implemented it. And I haven't heard of any competing standards either. To clarify, what I would like is something like a "sound accelerator". A sound card that would offload sound processing from my CPU while at the same time giving astounding effects that would be impractical to do on CPU in the first place. I'm not interested in absurd sampling rates (for the most time I can't tell MP3 and a CD apart) or uncountable channels (I'm using stereo headphones). But I am interested in special effects in games. Are there any alternatives or is Creative a monopoly in this market?

• Graphics artifacts/distortion with Win7 and nVidia

  - by Gepard

  Problem I encounter is rather hard to describe, so I provide a screenshot: http://dl.dropbox.com/u/1732760/video-distortion.png As you can see there are some horizontal stripes in random colors. These stripes appear sometimes in all windowed apps, games and on the desktop too. They tend to stay in place until I refresh window (or force it to to redraw by for example minimizing and maximizing again). They also tend to appear in the same place and shape multiple times, even if they disappear, it's very likely they will be again in the same place after a while. These artifacts do not blink or change if computer is idling. If I don't touch anything, do not use mouse, they will stay in place forever (unless some app redraws its window on its own). I first encountered this problem some weeks ago. Back then I thought it might be cooling problem, so I took out the graphics card, removed dust from the radiator and fan and put it into PC back. I also ran some stress test using Furmark (peak tempearature was ~65C) to see if the problem becomes more intense if the card gets hotter, but suprisingly no artifacts whatsoever appear during the stress test. Graphic card is Galaxy GeForce 7300 GT with DDR3 memory, was never overclocked. Drivers are the latest, from Nvidia site. OS is Windows 7 64-bit, updated. AMD64 3000+, 2GB RAM. I'm running a dual monitor setup with 2 19'' Samsung LCDs and problem is on both, so I assume it's not a monitor or cable issue.

• Computer makes odd noise. Replace almost every component. Computer still makes odd noise.

  - by ShimmerGeek

  My PC was getting pretty old, 5 years or so, and over the course of it's life I replaced the graphics card, HDD and a couple of sticks of RAM; but the PSU, processor, motherboard, fans etc. were all original. A few weeks ago, I started hearing an odd noise. I struggle to describe it, it sounded sortof like the 'click of death' you hear when a HDD may fail, but not quite... (And it was far less irregular) Also, I was sure I heard it once or twice a minute or two after I shut down the PC. This was going on very irregularly for a couple weeks. Some days I would hear no noise at all, others I would hear it often, maybe once every 30 seconds or so. I could find no common denominator - i.e. it did not happen more during gaming or any other intensive use. Anyway, I need my PC to sit some classes over the summer, so I put it in for them to run a HDD stress test and to replace a bunch of the components. I ended up replacing almost everything - the only elements I still have are my blu-ray drive and graphics card. They said when they started to run the HDD stress test it failed instantly (They started the test and it immediately said 'Test Complete' so they assumed it was at fault, and put a new HDD in since I was still under warranty with them.) I took it home a few hours ago, and I am still hearing the noise!!! Do you guys have any theories? I'm getting a little worried, I can't afford for my PC to suddenly fail during the next month - I have a lot of coursework to do. Any thoughts? Is it possible it could be the fan on the graphics card? I'm confused because it's so irregular. Any help would be much appreciated.

• computer randomly restarting. both in game and out of game

  - by eric

  first my specs are. AMD Phenom II x4 955 processor 3.2ghz 20gb ddr3 ram 4Gb Nvidia Geforce GTX 770 850w Corsair tx850w psu Gigabyte ud3 mobo Windows 7 professional I recently uprgraded my vid card to gtx770 and upgraded my psu to the 850w thats in it now. i did a reformat with the installation of the new gpu and psu and started fresh and only have a couple programs installed (diablo3, nvidia control panel, wow, and steam). all drivers are up to date and everything is hooked up correctly. the problem is it will randomly shut down. no blue screen. just turns itself straight off and reboots after a couple seconds. occasionally i will have to unplug the power cable from the psu for a few minutes then reconnect and it will start up. it seems pretty random. sometimes it does it when my pc is just sitting there on the home screen. and sometimes it does it during games. and sometimes it doesnt do it for days at a time. i noticed the psu felt hot so i put an extra fan blowing straight onto both the psu and gpu and neither feel overly hot after it shuts down now. could it just be that it is a psu problem. the psu was taken from another machine but wasnt having this problem in that machine. i have seen a few articles online about gtx770 doing the same thing. but i havent found any answers or solutions. any help will be appreciated. im sure the 850w is enough to power my machine, im just stumped and ran out of ideas to fix it. i have even returned the video card for another thinking it might have been an issue with that particular card, but still gettin the same problem.
