Random PC lockups.

As of the 12th of October I've been experiencing random PC lock ups, anywhere from 2 times a day, to the recent, none in 4 days.

I've been trying to replicate the issue so I can try and work out what's causing it, but I'm stumped.

Event Viewer dumps no valuable information that I can see.
Temperatures are fine and never really go high.
It always seems to crash while I have a video playing, although, that could be pot luck.

When it crashes the image goes stationary and the sound drags out the same note for a 'buzz' kind of sound. After a couple of seconds the screen turns grey and does not recover.

All fans and lights continue to run as if the system was running fine, which leads me to believe it's a GPU problem?

Windows built in memory test also shows no red flags. Would Memtest86 still be useful?

Any advice on how to diagnose would be great. Thanks.

Sounds like either a display driver issue or a dying GPU.

That's what I'm thinking. The card - GTX 770 - is only 4 months old, so I'm hoping not.

Well, sometimes you just have bad luck and get a lemon from the factory. If you have a spare GPU lying around (hopefully nvidia so you don't have to mess with drivers) you can try plugging that in and see if it fixes the problem. If it does, then it has to be a driver + GPU issue or a dying GPU.

If the warranty is still in effect on that 770 you could also try exchanging it for a replacement and see if that does anything.
