Alright so my computer started freezing on me from time to time a couple of months ago and now it freezes everytime I turn it on after being on for about 20 minutes. At first I thought it was the video card but i tried a different one and still froze. Then i tried different ram and still froze. Then a different psu and still froze. Im using the same video card, ram and psu on another computer and its running fine. So im thinking its either the motherboard or the cpu. I dont think its a heat problem cause I have a thermaltake Venus 12 cpu fan and 4 case fans. When it freezes I sometimes get a blue screen and other times I just get a bunch of line on the screen or the screen looks normal but you cant move anything. Anyone know what the problem could be?
