Computer won't power up

I have a Macintosh OS 10 computer that won't power up. The power went out, and it must have sent a power surge or something because the computer won't receive any power at all when the power button is pushed. is this a power supply or something  else?

The power supply is a good bet. Might be the logic board too.

Strung is probably right, but also check obvious things like a power strip that may now be bad or electrical outlet that may have a breaker tripped.

You may try to reset the p-rams.
You have to press CMD+ALT+P+R while pressing the POWER button.
Sometimes the power manager circuit hangs if the prams have  bad values (they are Parameter Rams, where the current date and time + various mac values are stored).

Try unplugging the computer for a few minutes, and if it is a laptop, remove the battery for a few minutes.  Reconnect everything and try the power button .

I agree on the power supply being the problem it is possible the the fuse inside the power supply or one of  the big capacitors on the power supply board have gone bad if so replace the fuse or bring a new capacitors instead of the old one with the same capacity

Can you specify the model? You should be able to see part number close to the power socket or on the original shipping box.
