Computer locking up whenever video/graphics are used

Hi All,

This is my first post here and I have a question surrounding my third build. My previous two builds run perfectly with no hitches.

I built this computer for my brother for his birthday back in his home town (400 miles from where i live).

Here's the components:

Motherboard: Asus P8P67 LE (REV 3.0)
Processor: Intel i5-2400
Video Card: EVGA 01G-P3-1561-AR GeForce GTX 560 Ti FPB
HD: WD digital caviar black 1TB 6.0gb/s (doa) put in a WD 500 Gb 3.0 Gb/s green drive
DVD/CD - OEM Asus 24x drive
PSU:Thermaltake 850W W0319RU
Case: Thermaltake Armor A90

I'll take you through the build:

Everything went fine during the build, everything looked good - booted up to bios with no prob. The 1TB WD black drive was showing up somewhat through the bios but showed 0.0 GB and no make/model and I couldn't install an OS. After some troubleshooting (I wish I was at home because I could have just popped in a drive pre-installed with windows) I ended up picking up another drive at a local store in my brother's hometown. When I popped that one in it initially didn't show. So I restarted and it was fine. I restarted a few times, and double checked connections and all was good with the drive. Thought I was through the worst of it....

After the Windows 7 64 bit home premium install, updates, driver installs everything seemed cool. As soon as I tried to play a game it immediately went to black screen and locked up. I had to force shut down. I thought it was the video card and (again I wish I was at home because I could have just popped in another video card!) so I uninstalled all the vga drivers, re-installed everything. Still the same problem, but I went even further testing it and anything video instensive - even watching youtube would cause the computer to hang, no keyboard/mouse access and either force shut down or after a few minutes sometimes it would turn off. If I ran the Windows experience index in the system control panel - as soon as the screen would flash it would crash - every time. Also, when watching video through the web it wouldn't immediately crash - it might play it for 1 min, 30 sec, 10 sec but it would always crash

So, I wiped the drive clean and installed everything again to make sure it wasn't software related - and it isn't, it's still having the same issue.

Right, now I'm back home (400 miles from the computer) and my brother is bringing it in to a local shop to have them check it out - but I don't want him to have to spend a fortune to fix it etc.

I'm stumped, it could be the video card, the PSU not giving it enough power, a motherboard issue.....or HD issue, even though I went through two drives....Everything is wired right (unless I've gone crazy!) I triple checked everything.

I would greatly appreciate if anyone has experienced this kind of thing before and can shed some light on it.

thanks and cheers

More about computer locking video graphics used
  1. Since you didn't specify...did you install drivers/up to date drivers? Not just GPU, but chipset/sound/etc.

    Could just be a bad GPU. I'd swap in a known working on and give that a try.
    PSU should be fine and rarely does a bad PSU let you boot.
    RAM is possible, I'd make sure it's manf spec in timings and v in BIOS and do a memtest 8 passes to be sure. Could also be screwy mobo.
    Doubt it's HD.

    Honestly, though, this is something you really just have to start part swapping to nail down. Take a look through our troubleshooting checklist (link in my sig) to make sure you didn't miss anything and start part swapping.
  2. Thanks for the reply!

    Yes I downloaded all up-to date drivers for gpu/chipset/sound/etc.

    I'll try the gpu swap first. Don't think it's the RAM, but I'll double check if the GPU swap doesn't yield any results.

    hope it's not a screwy mobo :(

  3. Yea, screwy mobo is usally the worst since it's the hardest/most annoying to test, and usually last thing you test.
