Help! Built GA-7DX system w/ xp 2000+ and it does nothing

[UCBPhantom]

I just built a system with the following specs:

Gigabyte GA-7DX mobo with Athlon XP 2000+.
512 MB (2x256) DDR PC2100 ECC, Registered RAM
PS: Enermax 365P-VE 350W

the rest is pretty much irrelevant to the question.

I press the power button, and nothing happens. None of the fans starts spinning, the only thing I see is a little yellow LED lights up on the motherboard. It's labeled DIMM CONN LED and the manual only says that it's on if there is enough power for the RAM. I have checked all connections (fans, power supply, etc etc etc) *many* times, reseated the memory, tried using just 1 of the RAM sticks, etc. Nothing seems to help. The parts are brand new (won them in the AMD XPP giveaway in santa clara). RAM was bought a few months ago but has never been used.

Please help! I'm freaking out here...would really like to get this thing up and running. Any advice highly appreciated. Thanks.

Hi there i think your problem is that your giabyte board is shoting out on your pc case i could be wrong but i have had this problem twice where you screw the board in the case with the board screws if you take the board out of the case and power up the board with the basic items in the board but make shure that the board does not touch the case you can check the holes in the board where you put the screws in to see that theres no coper track coming through the holes where the srews go in the hole you can take one srew out at a time and the power up and then go to the next one hope this helps i have just sent a board back with the same problem it powered up but did not start good luck

Have you made sure the power button connector to the motherboard is connected right? It will not power on if you have the power switch cable upside down.
