My power went out for over 5 hours yesterday, and when I tried to turn on my computer for the first time after the blackout this morning, literally nothing happened. I have no clear idea as to what is wrong with it (my best guess is the power supply is fried), but here is what I know so far.
1.) The computer was running prior to the blackout (it was loading a Youtube video while I was in another room. I didn't see it turn off and didn't go down to check it until the morning after the blackout.)
2.) When I tried to turn on the computer this morning, nothing happened. No front panel lights turned on, no case fans spun, nothing. Normally when the power goes out I can try to turn on the computer and the fans will light up and spin for a split second (back-up battery on the motherboard?) but nothing this time. This may be due to #1.
3.) The computer was plugged in through a surge protector, but it is a fairly old one. Everything else on the surge protector still worked, including two monitors, a wireless router, a cable modem and a set of speakers.
4.) My mouse has a blue LED that is constantly on as long as the USB ports have power (including when the computer is turned off). It was on this morning and stayed on while I tried to start the computer. When I switched off the power supply or the surge protector it turned off, but when I switched either back on the LED turned back on. I have no idea what that means, or how it is happening.
My system specs are in my profile, and I unfortunately don't have another PSU to test whether or not that is the problem, but I do have a multimeter if that is of any use. If anyone has any idea of what it might be, I would appreciate your help.
