How come the fan on my computer turns on for a second but then everything shuts off?
by Steve Crary on July 4, 2011Q: My desktop computer, when I push the on button the fan will come on for less than a second and then cycle off. The computer is not on long enough to boot. What do you think the most likely cause could be?

It’s either an electrical short of some kind or a bad Power Supply or even motherboard. If you still have any kind of warranty on the computer I’d suggest taking advantage of that or contacting a local computer shop for assistance.
