2. Corrupt windows files,
Repair XP by replacing corrupt files

sfc /scannow

in the run box, press enter and let system file checker find and replace missing / corrupt file in windows and explorer.This will take awhile to complete and you may be asked for the CD to be in the drive if windows is not preinstalled on the hard drive.

Take the side off and give everything a good blow through. Dust, in the Cooling fins and blocking the input ducts, can cause such a problem.
