Hello, first time user here.

I was playing XCOM 2 a lot lately, but unfortunately something happend with my hardware. I was playing the game mentioned and suddenly my computer froze, various artifacts poped up on my screen, audio hardware seemed to crash aswell and then the screen just blacked out. This whole thing happened about 3 times already, with about 3 - 4 days in between. I tried cleaning the insides of my computer which didn't help. I was monitoring temperatures inside with HWMonitor while gaming. The temperatures appeared to be normal, GPU was around 65C, CPU nowhere above 70C, motherboard with usuall 50C. I am a greenie with all this hardware stuff, but maybe the PSU is responsible for damaging the GPU. I have this computer for about 4 years and the PSU isn't that great so maybe it damaged the hardware over time. Oh and around 5 months earlier i had graphics driver problem. Problem happened anytime i entered any game, after about 2 mins same artifacts would appear as today, but the computer wouldn't crash it would just throw me back to desktop. I restored the drivers to older ones and it solved the issue. So my question is: what is going on with my computer and what could be the problem/solution?

Edit: i posted this before but i got no answers, so i am reposting. Right now my computer barely works. It works only in safe mode with artifacts on my screen. It completely died when i was watching videos on youtube.

Here are my specs:

Motherboard: ASUSTeK P8Z77-V LK
Graphics card: Nvidia GTX 560 ti
Processor: Intel I7 3770k
Power supply: Cooler Master GX 650w
