Hi,
I have a problem where on my old computer [I had to go get another computer

, but would still like to get the old one fixed] just continuously restarts itself over and over again without break and would just restart in an endless cycle of restarting itself all day if one did not turn it off.
The Computer is a Pionex with Windows 2000 Professional Edition.
I can't quite get much info without attempting to turn it on and then it is unusable in an unending cycle of restarting the computer endlessly.
Does anyone here have any idea as to how to remedy this problem?
