Hello. I believe my computer suffered some sort of power surge due to a lightening storm. When I left in the morning, my computer was on but when I returned home, it was off. I tried to turn it on, but got nothing. After several times of pressing the on button, it sounded like it wanted to start up...the fan came on for maybe 2 seconds and then evertyhing turned off. I tried connecting another power source from another computer and this time the computer sounded like it was going to start up...the fan came on for about 5-7 seconds and then everything shut down again. I tried the original power source in another computer and it worked fine so I know it isn't the power source. Now when I try either of the power sources in my computer, I get nothing at all. Any suggestions??? Thanks!
