Hi, I have a motherboard Asus P4S800-MX with a big problem When I install cpu and ram, I turn on and the botherboard boots. Then I turn off, and when i turn on again won´t boot. ( no display ) I install POSTCARD and shows no code but Reset light ON When I leave the Motherboard for a few days I try again with the same result. First time boots, I turn off, then turn on and nothing happend. It`s obviously that reset circuit is ok because tunrs on on first time. But something wrong is happening later..... Any advice?
