PC crashes while gaming, suspected GPU but need some help

Quick question about a potential GPU problem
A few times over the last month, my PC has crashed while gaming. My screen would be a blank color with lines down it, and I would hear a buzzing sound in my headphones. There is no message for "Program stopped working" or anything like that. I've tried moving my GPU to another PCI slot, but the same thing happened. Other threads I've read seem to indicate that it's the GPU or PSU. I don't have another GPU to try out, so I was asking here before taking it into a shop.

GPU is Radeon R9 270x

PSU is XG H800

The reason I'm unsure is that when it crashes, I'm unable to restart for varying amount of time (20 minutes to 4 hours), which I couldn't find in other threads.

Any help would be greatly appreciated, thanks!

  1. When it crashes does it show a gray screen with green vertical lines by any chance?

    It shows a blank screen, sometimes with vertical lines, of some color that was on my screen before it crashed.
    So earlier it was green and beige, other times it was different shades of blue.
  3. Yeah by chance I recently got the exact same problem with my R9 270X and I'm using a Coolermaster V850. Got the same result with older driver versions but not when using the iGPU so I ended up RMAing the card (still waiting on that).

    Alright, thanks dude, I was thinking of updating anyways, but just wanted to confirm that it was a problem with the GPU and not something more serious before I did replace anything.

    If you have one of the newer Intel CPUs you can always just try using the iGPU to confirm. It seems this issue isn't very uncommon with the R9 270X (at least relative to other cards). Take it out, try the iGPU, and if the problem goes away then just RMA the card. PSU can't cause visual problems like this.
  6. Thanks for the info, though I'm not sure how to test this using the iGPU as it only happens every week or so. Really just wanted to make sure it was actually the GPU that was malfunctioning before buying a new one.
  7. Try Furmark to test if the GPU is causing the issue. It pushes every part of the GPU to the limit so any problems should easily surface there (just keep an eye on the temps to make sure it doesn't overheat). I wasn't able to do this in my case because it was crashing even at desktop within a few minutes, but since yours isn't as serious then it should help you confirm the problem.

    So what should I expect to see running this test? If it is the GPU would it crash my PC again?
