1. Put heatsink compound on the CPU and button down the heatsink+fan again.
2. Leave the cover off.

HERES THE PROBLEM:
when i extract something big it tends to just turn off, or if i leave the pc on for about 12hours it turns off. Before i had the same problem while playing counterstrike 1.6 (gaming) i suspected it was my cpu(temp:82-5C) so i turn the fan to the max(current temp:64-7C) then it didnt happen anymore. im just wondering isit really my cpu overheating? or would it be my psu having not enough power? if its my cpu what should i do? my cpu fan is quite decent (at least i think it is).
