Looks like a BSOD? Troubleshooting

[Krush1m]

Guessing it's a BSOD, can't be 100% sure though.
Got it whittled down to GPU or Ram, guessing GPU based on the blurred image.

Bit of Back story:
Playing Games for hours on end, working fine, after about 6-7 games of Overwatch it does this. might do it once or twice in a session (6+ hours) and other days it will be fine. has only started doing it recently. GPU is about 3+ years old (November 11th 2014).
The only thing I have changed in the past 6 months has been Ram (16GB Corsair Vengeance to Dominator) and my CPU Cooler (From H80 to H110i).

Since tomorrow is a public Holiday in Aus, trying to troubleshoot best I can without anything to try at this point, and hoping for a few educated guesses.

Looks like a dying GPU, you get this distortion also while playing or only on the BSOD?

Only on the BSOD.
Woke up and realised my CPU was overclocked to 5.2Ghz, which could be the issue. As that was a recent change as well.

Dropped it back to 5.1 and it's running fine, turns out the only issue was I'm forgetful.

Have you been running that at 5+ ghz since 2011 and not added voltage ever since? When my 2700k hit 2 years old i get blue screen once every year and i turn offset voltage up a notch and i wont see another blue screen for another 1-2 year. CPU degradation and all. That was til i upgraded last year
