I think it should be something with the Gpu and heatsink not making good contact in my opinion.
yeah this is what I originally thought when it was first happening to me, I am still not sure what the exact cause is, but I did find a fix, and thats the link I posted further up the thread... So I did add more Arctic Silver, and you only need a rice grain sized amount...
I'm really not quite sure bout this problem, my best bet would be GPU overheating/ not making contact due to shitty X-clamps... Its fixable, if you want to waste a few hours and go through a buncha BS and buy the screws and washers from Lowes and fix it.
Cus if you modded it or opened it, Micro$oft aint fuckin with you, lol
