Hello dear Quakers. I've got a problem and I wholeheartedly hope you will help me because it has been bothering me for many months now and I don't know any other place to go for advice.

Intel Core i7 -3770 CPU @ 3.40GHz
32GB RAM
GeForce GTX 660 Ti
64 bit Windows 7

The problem is that when I try to play games that require even a little over average requirements they just shut down.

What happens:

CS:GO works 10 minutes max before it crashes down with a common "close/report" table

any HOMM above IV ends up in the same shit as CS:GO

CS 1.6 goes the same scenario but not always, sometimes it's good for a couple of hours while the other day it works for 5-15 minutes before it will crash. But it's really random because after crash I can play it again for hours or it will crash again.

Quake Live didn't ever bother me with these kind of problems.

HOMM III works perfectly fine too.

If that anyhow matters I cannot record videos with fraps too, it will ALWAYS crash by the end of the loading bar.

So based on these indicators you may conclude that the higher the game's requirements are, the more there is a chance to encounter problems.


What I tried:

Cleaning the box with the hairdryer and a brush.

I've tried to see and increase the fan speed with the SpeedFan app. None of the fans were working full (64 max) according to this app, so I set it all on 100 and it didn't solve anything. Although I didn't hear that it started to working louder after increasing their speed.

Please help or recommend any good site.
