PC dies/crashes with monitor having random colored stripes after playing demanding games for some time, what could possibly cause it?

It hasn't occured to me before, can't recall after what it exactly has started. Sometimes the audio keeps looping when it happens, sometimes the screen goes out but I can hear game's audio going on, enemies hitting me etc. Sometimes I can even hear beeping coming out of PC when this happens.

Sounds like overheating or an unstable overclock...whats your vid card and current clock speed? could also need a good cleaning open up the case and make sure the fans aren't packed with dust and are working.

I've kept my eye on temperature, my CPU (i7-3770 3.40GHz) as about 50 celsius, while GPU (ATI Radeon HD 7850) at max goes up to 65 celsius. I guess 65 celsius is a cap then?

And now that you mention it, I think there might be a problem with a fan since. I haven't payed attention to this before, but fans seem to work somewhat more quiet than before.

Likely a soft cap in the fan profile. have you overclocked with any software such as afterburner,precisionx or the likes?

No, there isn't. I reinstalled Windows just for this problem, and reset BIOS to default, so it cant be capped.

Pc bios doesn't control the gpu it has its own bios the fans are controlled in stages as it reaches a certain temp the fan kicks up to a certain% if the card is overclocked and seems stable a certain fan stage could make it unstable because it starts drawing more voltage and takes it away from the core which is why we asked if the card itself was overclocked.

Oh, alright. By the way, I have looked into my PC case, cleaned it up. All fans are running, it's just CPU fan which got capped for some unknown reason. It has it's own controller on backside of the case, and it fan doesn't react to it anymore. Seems like I have more problems than I've thought :\

The fan is not working at all? shut down that pc until you replace it or you could burn up your processor!

It's working, it's just that it doesn't react to manual control thing on the back of PC.
