It's likely but not impossible that your PSU surged. Modern PSU's are generally good at containing the shock to stop other components of the PC getting damaged by electricity. Generally the main issue with turning off the system from the wall is data corruption as the system doesn't have time to save and empty caches on shut down. Try another PSU if you have one to spare.

This may sound weird, and it's a long shot, but try:

1) Unplug power supply
2) Remove BIOS battery
3) Hold down power button for 20-30 seconds
4) Reinstall BIOS battery
5) Plug in power supply
6) Power on the computer

It may be possible (though unlikely) that, if the power supply has a replaceable fuse, that the fuse blew. You could check for that as well, though that generally requires opening up the power supply.

and by BIOS he means CMOS battery

Yes! I really need to get out of the habit of using BIOS and CMOS interchangeably like that.
