What temp is your CPU idling at if its around 60 then that is way to high for idle. I have an i7 and it idles at 40. The GPU could also be over heating for have a buggy driver. My laptop for example (Nvidia GPU) will not run on any newer drivers than one from April of last year. If I install a newer driver the mouse and keyboard lock up and the screen freezes. No BSOD, just locks up.
