Computer doesn't boot after dusting

  1. Hello,

    So I've encountered a problem with starting up my PC that I built myself. It's been a while since I've cleaned the inside of the PC, and today I took it outside to dust it with a compressed air can I got from Fry's Electronics and a Swiffer duster. The PC was working just fine before I took it outside to clean.

    The PC powers on, but then powers off after a couple seconds, and then powers back on. But when it it's on, it doesn't recognize my monitor, mouse, and keyboard. I'm assuming that it's not booting up properly. From the google searches I've done, I've found that it could be dislodged cables from the compressed air can. What I've done so far is detach all the cables to the motherboard and attached them again, including the jumpers and video card. I also tried turning it on by positioning the PC differently.

    I cleaned it with the compressed air can along with a skinny tube to reach hard-to-reach places, but I think I held the can in a bad position and caused it to shoot very cold air onto the motherboard and power supply. I have a feeling that this caused the problem, although I'm not sure.

    I just want to get some input before I end up bring it to some shop to get it fixed.

    Thank you!

    As you know the more you use compressed air the colder the air (and can) become. Just a guess but if the air outside was warm and especially moist and the colder air met it could have formed condensation especially in those hard to reach places. Again, this is only a guess but it is not out of the question.
