I recently bought a new cpu (Athlon II x4 propus 620). So I go and play gta 4 then all of a sudden my video card fan starts spinning faster and faster until my computer hangs and I start hearing loud high pitch noise. All in a 1 minute time frame. I quickly hit the reset button and everything seems to be back to normal, as in nothing was damaged luckily. Is there a way to fix this, there must be something wrong with the video drivers or something to do with the cpu. Please help. BTW I got these temperatures after I rebooted my computer. Video Temperature: 54C CPU Temperature: 43C Also I have the latest driver. My board also has the cpu listed in compatibility list. I tried to see if there was a voltage problem Im also a little scared to do anything beyond this point, if it happens again i might not be so lucky.
