Not getting any power

[KoolAidMan]

So my computer has been working fine for the last 2 years, but the other night when I went upstairs the monitor wasn't getting any signal. I turned it off and tried fixing the monitor cable and then replacing it, but this didn't help. So I turned it off again and figured I'd just work on it in the morning.
I tried turning it on again just to see what happened and all I got was about a second of power and then everything just shut off. Since then I don't get anything. I've tried 3 power supplies, taking out different sticks of ram and replaced the power cord and plugged it in in a different room. None of this has done anything except occasionally getting another quick blip of power.

My thought is that it is probably a motherboard problem. Does this seem right? If so, is it something I could try to fix, or would the board simply need replaced? Or maybe I'm completely wrong and it's something else. If anyone can give me any ideas that'd be great.

Thanks

Could be a short or ground problem. Try to unplug and reseat all your power connectors esp the one on motherboard and and reseat any cards like video. Also I am assuming your not overclocking the system.

Correct I am not overclocking anything. I have completely disconnected everything and put them back in and nothing has seemed to help so far. I guess I can try that again.

Have you tried resetting your BIOS?
This is a nice item to add to your toolbox.

Sounds like a short/ground problem. Make sure any bare wires are not touching your mobo.
