Computer fan malfunction

I have a computer by Emachines that has Windows XP. Occasionally, my hard drive will just shut off by itself. I know that a virus is not the problem because I have scanned with AVG, found 1 virus, and removed it. Maybe this is due to my computer fan? When I start up my computer, the fan located next to the power cord (the fan that I assume is intended to keep the computer from overheating) often malfunctions and spins weakly, as if it is going out of power. I have to tap it with a pen in order to make it spin at all. It also strains during computer usage and makes revving noises. As a result, my computer gets really hot, and just shuts off randomly.

Can someone please help me with this frustrating issue? I would deeply appreciate it.

Thank you in advance,

Gared

Modern Computers will shut off to protect themselves from overheating (called thermal protection)

The case fan you seem to describe is generally not the primary culprit in this--it's job is to remove heat from the case---the really critical fan is the one that sits atop the CPU

anyway, you should check the PC's temperature


download Everest the Home

at rest, your cpu is pushing 62 degrees celcius

That is on the very high side if your pc is at rest/idle--the temp probably soars when doing heavy work.

Everest is only reading one fan--not sure which. Should be at least two...and the speed seems a little slow for a cpu fan (should be nearer 5000)


First thing I would do is open it up and clean the dust bunnies out of the cpu fan. (hold the blades and hit it with a can of compressed air--hold the blades because the compressed air will spin the fan so fast it will burn out the bearings)

Thank you--and compressed air can be found at most computer/hardware stores?
