    All of the above as well as a new 500GB SATA HD and a fresh copy of windows home premium.

    When I first fired up the computer I worked for a couple of minutes and then the computer shut itself down. It wouldn't power back on at all. If I unplug the power supply and plug it back in and turn it on the computer turns on only long enough for the motherboard LEDs to flash on and then it shuts itself off again.:bang:

    I'm far from a genious when it comes to troubleshooting, all I could figure is maybe the motherboard is defective. I'm coming here for helping hoping someone from this GREAT:) community can help me out a bit.

    Thanks in advance!

    Any beeps?

    Assemble it outside the case (on the box lid or other non counductive surface) with just the basics, 1x memory, cpu, vid card, hdd, case speaker.

    See if it will pass POST

    Ok, so as far as I can tell it's working.

    I pulled out the PSU and connected it to a case and and shorted out the 24pin connector to test it and it worked. I slowly hooked up everything else and voila, it's working.

    My Antec case is a bottom mount so I had flipped the PSU upside-down so the fan would blow up into the case instead of towards the bottom of the case. As far as I can tell the only difference is my PSU now right-side up.

    I never thought having the PSU upside-down would make a difference (It hasn't in my other builds) but apparently with this PSU it did?:3eyes:
