A few days ago, the main breaker in my fuse box tripped numerous times in my house thus causing my pc to shutdown improperly. Now, whenever I turn on my pc, the fans and lights would light up for a second before shutting down. The only way to get the pc running is to keep pressing the power button repeatedly. Could the psu be damaged? I checked the connections behind the power button and to the mobo and they appear tight. Once the pc is up and running though, it appears to operate normally. I have a good surge protector connected. Please advise.

The PSU could have been damaged. I'd start with a new PSU and see if that's it.

Last time something like that happened here the whole computer blew up so yeah the PSU is probably damaged. I suggest you borrow someone's PSU to test and then buy a new one if it fix the problem.

It comes on after a few trys?
Hold in the "ON" button for a full sec and see if it boots,if so the circut in the PSU that tells the MB that pwr is on all the way is cooked.

It seems to power on erratically. Sometimes, if I hold the "on" button, it will fire up on the second try, if not then not at all. Right now though, it's been booting up on first go like normal so I don't know what's up with the pc. I will keep monitoring the situation and see if it returns to previous state. I will try a new psu if need be. Thanks all for your input and advise.
