PC not powering on

  1. I have my old computer I was getting ready sell by reformatting it when it just shut off. I turned it back on but it only stayed on for a few minutes before it just shot off. Now it won't even turn on. I have tried another powersupply but that didn't work. Sometimes when you flip the power switch in the back of the power supply the fans twitch a little and the is a high beep that sounds like the beep a computer will make if the power supply isn't plugged into a high in graphics card, so then I thought it might be a graphics card and a tried another graphics card but it still didn't work. It wouldn't matter if the hard-drive was fried would it? it should still power on right. So leaves the cpu and motherboard.
    I was just wondering if you guys had any idea what the problem could be.

    Here are the specs

    CPU-AMD Athlon 64 3200+
    Motherboard-ASRock K8 COMBO-Z
    RAM-1 GB of Rosewill pc 2700
    Hard Drive-160 gb hatachi
    Vedio Card-Evga Geforce 6800

    Try another power supply first. The motherboard or a corrupt bios can cause this too

    I read all of your post. My motherboard power plugin (24 pins) was going bad. If I wiggled that junction of wires @ the board while trying to power up, I could get it to work, for awhile. This may not be true in your case. Good Luck.

    I have already tried two power supplies and I know one works because I put it back in my other computer and I am using it now. I will try wriggling it next to see if I can get anything, and just to make sure you guys think it is probably the motherboard and not the ram or cpu? Thanks for the help so far.
