PC won't turn on after power outage

[katsuai]

Hello all, as the title says my pc refuses to turn on at all after we had a few seconds of power outage this morning. It's a standard HP pavilion s3750t if that's any help. I don't know about any other specs but it's the standard factory ones except for the gpu which is Radeon HD 5450.

It worked fine the night before but now there's not even a light blinking. It's plugged in to a surge protector and it was asleep. Tried plugging it somewhere else but nada, and the other things plugged on the same strip works. I even tried a different power cord. Could it be a fried power supply?

Although replacing the power supply will fix the problem, there is nothing wrong with your power supply or your computer. This will happen every single time you lose power with an Asus MB. Unplug the computer and hold the power button in for 10-30 seconds. Usually you will hear a popping sound when the MB discharges.

If that doesn't work, unplug the 24-pin connector from the power supply to the motherboard. Again, you will hear a pop when the motherboard discharges. Reconnect the 24-pin connector, and the computer will start normally. Because disconnecting the 24-pin connector fixes the issue, that is why replacing the power supply (completely unnecessary) will also solve the problem.

Tree branch fell knocking out the power when I was on my computer. Power restored, and I tried to turn on my computer, and nothing. There was a green light on inside the case, but as stated, the computer would not come on. I turned on my son's computer which was not on during the power outage, and it booted right up. Searched around a bit, and I found this thread. I do have an Asus motherboard, so I tried what was suggested. The first suggestion, holding the power button in, did not work. So, I unplugged everything from the case, walked into the kitchen, opened it up, and disconnected the power cable from the PSU to the motherboard. I did not hear any popping, so I was concerned. Sealed back the case, brought back to the computer room, plugged in the power cable, pushed the power button, and the computer started to boot. This solution worked for me. Thank you very much, as this saved me a lot of headaches!
