How do I diagnose graphics crashes after GPU and PSU swap-out?!

Hi all,

I don't know where to go next in diagnosing my PC problem. The symptom is simple: in various Blizzard games (SC2, Heroes of the Storm, WoW), the screen will stutter, freeze, and then either silently recover, recover with a Win10 "Your driver has recovered from an error" toast, or on rare occasions crash the game completely.

I don't play many non-Blizzard games on PC so I can't really say whether it happens in non-Blizzard engines, but with the swap-outs (below) I would be extremely surprised if this was engine-specific.

The PC is otherwise completely stable during normal desktop usage.

I've swapped out my GPU (GTX660 -> R9 270) and my PSU (Corsair 550w -> 750w), assuming one of those would be the culprit, as the problem only occurs under load. However, the problem hasn't gone away.

A six-hour Memtest showed no problems with my RAM. I've also run a couple of PC stress test suites, none of which have shown any errors.

I can post a DXDiag later-on should that be of any use.

Where do I go next? Any more swap-outs and I might as well have bought a new PC. Any help much appreciated, Guru's!

Edit: I would love to post my DxDiag but I can't attach files and the editor insists the dxd output is full of image tags.

This really sounds like a driver issue. If you are still running the Nvidia card, get the latest drivers from the Nvidia site and see if the problem continues.

Hi, thanks for the reply! I'm actually running an AMD part now and used Driver Sweeper to make sure the system was virgin.

I guess a full reinstall might be on the cards, but I'd like to investigate other solutions first. 🙂
 
I hope that works. I know there have been people coming to the forums, reporting difficulty in changing drivers from Nvidia to AMD and vise versa. But there could be thousands of people out there that do it without issue, so who knows. Driver sweeper sounds like a good plan though.

If that doesn't solve it, I would start looking at GPU temperatures while gaming in windowed mode.
 
Okay, a clean Win10 reinstall did not solve the problem.

I also did a substitution test on my RAM to ensure that there were absolutely no problems there, and there weren't.

If I was at a loss before, I'm stumped now.

Would SATA or HD issues manifest as graphics hang-ups?

Could there be a PCI-E problem on my mainboard, and if so, how would I diagnose it?
 
Thanks for your post!

Yes, this is with latest Catalyst. I use Open Hardware Monitor for system diagnostics, I will post a grab of that when I can.

How can I attach files or post large blocks of text here?
