  1. Welcome to Tom's Forums! :)

    It seems like, hopefully, a bad PSU. Do you have another that you can borrow from another Workstation/PC?
  2. Do you mean Power Supply Unit?
  3. Yes, PSU = Power Supply Unit.

    Dang, put in a brand new Power Supply system still does the same a little fan or noise for a few seconds then stops and repeats. Should I try stripping out all video cards and doing a boot?

    No Bios comes up Nothing Black Screen

    I replace Power Supply same thing Black screen No Post No BIOS no beeps just flashing light on from for a second then all stop then trys to restart again.

    Next Step? Take out all video cards see if boots,

    take out ram chips see if boots,

    Thing has a battery in it someplace see if it is dead I guess?

  7. Mine had these same issues. It wouldn't power, and it would just start to power on, but power off.

    I took jumper J25 and set it so that the CMOS settings would reset. Upon doing this, and performing the typical power on/power off, moving J25 back in its original position, and then powering it on, it was working correctly (once I set the BIOS settings back).

    Bizarre that it made the entire system not boot.
