My comp has recently been hanging while i am using it and the internal temperature increases very fast. From example 20 degrees to 40 degrees in minutes... I have only 1 giant fan working but up till recently, it was doing fine. My PC is overclocked...
Wonder if anyone can tell me if it is my CPU fan not working efficiently enough or is it a software problem?
Remove your heat-sink and wipe away the old thermal compound. Then reapply a new compound and reseat your heat-sink. At the meantime, you might like to clean the CPU fan too.
