Computer comes alive after 36 hours We had a power surge/spike in the afternoon and all the appliances/gadgets in the house restarted on their own. However my home computer froze with a blank white screen and none of the buttons would work (shutdown/restart). Finally I had to kill the power supply to shut it down.
But when I tried to start it up again it was dead. The motherboard's green light was on but none of the fans/beeps/drives ever worked. I tried all the known techniques (draining power by holding the power button, resetting the CMOS, trying out different power supplies etc.) but to no avail. So I went ahead and ordered a new motherboard.
But about 36 hours later today, when I came home, the computer was already switched on on its own and functioning perfectly. I could restart it and it looked like nothing had ever happened.
What do you guys think could have happened? My friend says that some of the capacitors on the motherboard could have taken some time to discharge. What do you guys say? Also should I still go ahead and replace the motherboard or is it still good. It's about a year old.
PS: I have already ordered a UPS now. Didn't have one before.
