  1. When I turn on my computer all of the fans come on, but none of the
    drives will start working. sometimes the fans will stop running after
    a couple of minutes, when I start it back up the fans go on and
    then shut off right away but still none of the drives or the monitor come on

    Sounds to me like a dead PSU.

    Have you made any changes to your system lately to cause this problem?

    Could also be your motherboard. Take a look at it. Any swollen capacitors?

    No I have not made any changes, I was thinking it might be the PSU
    but I thought I'd get a few opinions before I get a new one.

    If you have another one to test, that would be a good starting point, but most people don't.

    You can test your PSU if you have access to a voltmeter:

    Other than that, you can just buy a new one. There are good quality PSUs on newegg for $50 or so. Look at the fortron lineup for example. Nice psus for cheap.

    If that doesn't fix you up, the next suspect is the motherboard. Did you find any swollen capacitors?

    No all capacitors look good. I'm going to pick up a PSU and try it out. thanks

    If I can make a suggestion on the PSU....

    First go here and calculate how many watts you need:

    Then be sure to get a PSU with dual 12v rails, and at least 12amps on each, preferably more (depending on what kind of system you have of course. If you have a high end graphics cards and a dual core CPU then you'll be wanting more like 15 or more amps on each 12v rail).

    Good luck!
