lots of times what happens is that the motherboard is shorting out or slightly touching the case somewhere....to find out what you do is take the board back out of the case and try booting it outside of the case...what you do is strip out all the extra cards like nics/sound cards/modems etc....get it down to just cpu/heatsink..one stick of ram..vid card......take th emotherboard out of the case and set it on the motherboard box on the antistatic packaging......

Just wanted to point out that you should NEVER set your motherboard or cards on the outside of your antistatic bag... ONLY the inside is "antistatic",... the outside is usually metallic and can cause shorts... not ALL bags are this way but most Mobo bags are... its best to just set it on the bare cardboard...
