I have a Dell Optiplex GX150 loaded with Windows 2000 Professional. It has begun to restart whenever I tell it to shut down. If I press the power button or click start, shutdown then it will still restart. The only way to shut the machine down is to hold the power button down.
The machine runs great and my virus protection tells me that I don't have any viruses, spyware and/or adware. Any help is greatly appreciated.
