Question about Dell Dimension XPS 400 PC Desktop
Haven't used the computer in a while and would not turn on. Unplugged and tried to turn on and shut off within seconds
Unhook each device from the power supply,
one device at a time except the mother board plug. If it stays on when any of the devices is disconnected that is the one that is causing the problem. If this doesn't give results try a known good power supply. Or if you have added a lot of devices to your unit you may need a power supply with more wattage. If none of this helps it may be a more expensive problem like a bad motherboard. Also test your memory one stick at a time. This is all I can think of right now but I may think of something else later.
