Sounds like you may have a grounding issue or something. make sure you dont have a mb mounting peg somewhere it's not supposed to be.
Other things to check:
Bent pins in the MB socket
The 8-pin aux CPU power lead is plugged in
Memory properly seated
You might need a fan connected to the MB's CPU fan header for initial boot.

You can also try disconnecting everything from the motherboard except one stick of memory, the video card, just the bare essentials needed to get into BIOS.

First, check and recheck that the ram sticks and the video card are firmly seated in their slots. Same with any other add on pci cards you may have installed in the motherboard.

Also make sure you have both 12v power leads connected to the motherboard. The main power lead is has 24 pins and the secondary one has 4 or 8 pins. Both have to be plugged into the motherboard for the system to power up.

Third, your video card requires direct power feed from the PSU; one, maybe even two connections. Make sure you have those in place.

If these first three measures don't solve the issue, then remove all but one stick of RAM. If this doesn't impact the problem then remove components from the case and set them up on top of a box or table top. What we call "bread boarding" it. What you describe sounds like it could be a ground out problem. It's very easy to have one of the mounting studs misplaced or have an extra one on the motherboard tray that is grounding out against the circuitry on the underside of the motherboard.
