I am writing this on a separate computer than the one that is having troubles. That one is right over there.
It suddenly became irritable: shutting itself off for no apparent reason. It would not reboot, so I took the panel off the computer (it's an AMD XP running windows XP) and found that my thermaltake 5 heatsink/fan combo was not spinning.
I aimed a small desk fan in there and cooled it off a bit before rebooting. With the desk fan cooling its insides, the computer seems to run fine.
However, I was reading another post on G2G and i saw that there may be some default setting in my bIOs that is overriding my heatsink's fan's function.
The computer is running at 61 degrees even with the desk fan (I learned that through the Everestt Home Edition ... man isn't that a sweet program).
I would appreciate any help available as this is the art director's computer and we are three days from deadline!
