No power

Folks:
I have a five year old dell computer. While using I had a quick
power outage. The power went off and back on in a matter of
three seconds.Now my computer will not turn on. Is there
a fuse or could it be something else? I would appreciate any
and all responses. Thank you in advance. Ron

Do the fans still run? If not it may be the power supply. Doesn't take much to fry an old capacitor. Never seen a fuse on the power supplies I have had. On that though I may be wrong.

Pull out the 5"x5"x5" power supply cube and look for internal fuses.

I wouldn't open the power supply if I were you. There are hazardous voltages in there. The surge of the power coming back on probably killed the power supply. A 5 year old Dell may have a standard power supply that you can replace with one from a store such as Best Buy, or you can order a new one from the internet

My question is was your computer tower plugged into a power bar or directly to the wall...? sounds like a surge may have got you...if it was its a matter of finding out what parts are fried

If the power supply fan spins, then you can try to reset the motherboard. Most motherboards have a jumper that can be moved that will reset it. Or you could probably remove the battery from the motherboard and let it set for a minute. Reinsert the battery and try again. Just know that you may have to reset the bios.
