While my pc was on, I accidentally turned off and turned back on my power supply instantaneously, which turned off the computer. Now I am unable to boot the computer. I tried bridging the front IO power pins on tho mobo and still no boot. I’m not sure if it’s my power supply either, which it’s very possible that it is. I tried plugging it into different outlets and still nothing. All my front IO panel pins are connected properly. My idea is that either the motherboard is fried due to static or that the power supply is fried because of switching it on/off instantly. Also all of my 24 pin and CPU power connectors are connected properly.

Ok last thing may be. Remove the cmos battery of mobo wait for few minutes and put it back on. Then install any working PSU (not your old fried one as you have confirmed it is not running in paperclip test) and try to start it. One important and funny point to note, the CPU EPS power connector and the PCIE power connector looks same but don't put the pcie power in cpu it will not work.

MERGED QUESTION
Question from tsingos.reid : "Unused thread (lock)"



1. Do your mobo has any lights? if it is on or not? When you try to on your pc turns on for a second and turns off or it is dead?
2. Remove your PSU 24pin mobo connector and try to jump start it with paper clip if it turns on then it might be ok.

Please don't do that. Just let a mod know and we'll fix duplicate posts. We're aware the forum's buggy right now. :)

- first try to turn switch off your Power supply button, disconnect the wall power outlet cable and let it sit for few minutes then try to power back on the system after disconnecting any non necessary hardware from mobo and PSU ( like optical drives or hard drives or add on cards)
- swap in a spare PSU or test your PSU wth another mobo.

yeah I skipped telling you about the paperclip one ( I used it couple times) because of the liability lol, anyway motherboards are cheaper nowadays, you should be able to get a replacement one on ebay in less than a week, sorry for your loss, or maybe it's time for the mobo upgrade you've been delaying for so long :) good luck with the rebuild.
For curiosity sake: what PSU and motherboard do you have, I thought modern motherboards and PSUs were equipped with some circuitry dedicated for protection against such event ?
