Power Supply ok, but won't turn on

  1. 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!

    Hello and welcome to Techspot.

    Mmm doesn`t sound good.

    Open up your computer and disconnect everything that`s not required to boot.

    I.E just leave the hdd cpu psu and ram. If your computer starts to boot normally, then start adding the other components one at a time, untill you find the culprit.

    If none of the above works then I`m afraid that your mobo maybe dead.

    Regards and good luck Howard :wave: :wave:

    I agree with H²

    Lightening can be tricky stuff.
    Should you find out the MoBo is gone consider:
    surge protectors for any other electronics you still have. :eek:
    keep posting back
