Is my GPU kaputt?

Hey guys.

I've tried searching around and it does in fact seem that my card (Sapphire Radeon 7970 3GB OC) has some issues with crashing, but I want to make sure it's the GPU before I ship it back.

Bought it in May 2012, it crashed once (gray screen) when I was playing Crysis 3 on ultra last year, figured it was a fluke and moved on.

But now it's crashing pretty frequently, nigh every day, even when doing stuff as simple as browsing the internet. It'll cut the display, it sometimes comes back (pretty rare), but most of the time it goes to a random screen of white/green/gray/black and I have to restart my PC. Recently, it's been slow to bring up my desktop upon rebooting (log in window comes up, enter password --> black screen for ~10 seconds before the desktop appears.)

I thought it might be a temp issue, but I cleaned out my case and the card itself (still a little dust left on the heatsink that I couldn't quite get to), installed GPU-Z, and it idles at 25c and maxes out around 60c when playing something like AC4 (the room, since it's been so cold, is about 65F). All my drivers are up to date.

My CPU is cool as well (~25-30C). I ran a Windows Memory Test and it didn't find any problems with the RAM. The only thing I haven't checked is the MB/HDD, but it doesn't seem like those would cause this kind of crash. I'm not too good at BIOS stuff, so I guess something could be wrong in there, but I don't see what would have changed to make it crash now.

General stats:
GPU - Sapphire Radeon 7970 3GB OC edition
MB - ASROCK z77 Extreme 4
CPU - Intel i5-3550k (not overclocked), upgraded fan
Power Supply - OCZ ZS 750W
RAM - G.SKILL Ripjaws X Series 8GB (2x4GB)
Windows 7 64bit

Built it in May 2012, didn't really have issues until around Thanksgiving of this year. Thankfully the card is still barely under warranty, I just don't want to go through the hassle of sending it off for no reason.


Thanks.

Make sure your motherboard bios and all windows and GPU drivers are up to date. If that doesn't at least help then it may indeed be kaput. Are you confident that your PSU is supplying enough power? That would be the only other thing I could think of.
