Windows XP shuts down after 2 minutesLocked
Windows Xp was running on a Tripp Lite UPS unit and the UPS went bad. Shut down computer normally and bought an APC UPS. In Power Options, no UPS was selected on either unit. Computer is set to go to standby after 20 minutes. Ever since the computer was shut down, now when it starts up, it stays up for about 2 minutes and then shuts itself down. Does not matter if it’s just plugged into the wall; still does it. Help!
