Computer keeps shutting off

[bat_boy77]

About 3 months ago my pc would work fine but recently it shuts off then comes back on or just stays off. after it shuts off I have to turn the power supply off and back on again before it will turn on again. Any help?

An overheating power supply, due to a malfunctioning fan, can cause a computer to shut off unexpectedly. Continuing to use the faulty power supply can result in damage to the computer. You should replace it immediately if this the only problem.
