After an electrical surge my computer is dead, nothing powers up. A friend thought it mught be a fuse. Is there such a thing and where would it be in the computer?
There usually is a fuse in the power supply of the computer, but because of the capacitors and such inside of the power supply I would advise against opening it up.
Just get a new P/S, hook it up to the computer and see if the machine will work then. I generally will just unplug everything from the old P/S and then plug in the new one before actually putting it in the case just to make sure it works. If it does, then I unscrew the old supply from the case, install the new one in it’s place and then you’re good to go.
More often than not it’s just the power supply that’s dead. They’re built to die before anything else in a surge, which is nice, cause I’d rather replace a $50 power supply than a $150 motherboard and a $200 processor.
