My motherboard wont stay powered on

Feb 27, 2010
  1. Hi, I have a ASUS Crosshair motherboard. I upgraded from my old power supply that was 500w to a Antec TP-750 that is 750w . My MB worked for a couple of minutes and then shuts off instantly. I powered it on again and it shuts off instantly about 10 seconds after the boot screen. The MB don't want to stay on at all. Can anybody tell me what is going on with the motherboard?

    You can try using you old power supply again ( if it isn't defective ) and see if you MB works again. If so, there could be a problem with your new Power Supply
