Will not power up

[bunkachunk]

I have a HP PAVILION A1101A, asus p4gv-la mobo, celeron 2.9 d socket 478 processor. My problem is that when I turn off the pc, then the next morning I went to turn on the pc there is no power. I swiped out the power supply and all was fine for about a week, then the same thing again, no power. I put the old power supply back in and it fired up,no problems. a week later again whent to turn it on, no power, now, no power supply will work. I have three power supply's all deferent makes and power wattages, none will work. I can not see any bad spots on the mobo, top or bottom. Any ideas whats going on?

Could be a bad board or ram stick. You may find an identical replacement board on ebay. You can troubleshoot by removing ram sticks or disconnecting devices one at a time until the board posts consistently.
