Hey,
I've been having issues with my computer for a few months now : it randomly freezes with little square artifacts on the screen (looks like this : http://imgur.com/AwzT7tg). Sometimes it "only" crashes the NVidia driver but it recovers after a few seconds, but most of the time the screen goes black after a few seconds and my only option is to reboot. I noticed the issue happens more frequently after some heavy use (like gaming) or when the fans blow faster. Sometimes it even happens during boot : the BIOS screens are not scaled to whole screen as usual and are filled with artifacts, and finally Windows fails to boot. I usually have to reboot once more when that happens and the issue "fixes" itself.
First, my specs :
Most components are 5 years old (Nov. 2011), GPU is from April 2014. I built it myself. I immediately thought about a GPU issue, so I tried to swap my GTX 760 for an older GTX 560 I had lying around but the exact same problem happens, albeit less frequently. The GTX 760 itself seems fine since it's now used in another PC/media center without any problems.
Some more info :
I'd like to know if anyone had encountered the same problem and what component might be at fault, so I know what I'd have to replace. I thought about the PSU starting to fail, or the motherboard itself, but my knowledge in hardware issues is lacking.
Thanks a lot in advance for any ideas you might have!

Intel Core i5 2500K
Cooler Master Hyper 212 Plus

Some more info :
No recent hardware changes, the problem seems to have appeared on its own
No recent BIOS updates either
Airflow in the case seems good, temps are normal, even during gaming (GPU ~80° C, CPU ~60°C)
Tried with a few different NVidia drivers, including the one I had been using before the problem started appearing : no difference
Tried both GPUs in the 2 different PCI Express slots : no difference, the same problem happens
Screen is usually plugged with DVI, and I tried in HDMI and with another DVI cable : no difference.
