I finally got all the parts, and after reading the manual and setting up quadruple checking, go figue nothing happens. Its a P4S800 (Asus) Pentium 4 system.My flat panel is a Dell and has a light that tells it when it gets a signal. When I push the power button, the case comes on, processor fan comes on, a second or two later the monitor displays the gfx card stats (128Mb etc etc) and then everything shuts off, the lights on the case, the fans, everything. I ahve been collecting the parts for a month now and this is a real let down. Anyone have any ideas? Thanks, John...Oh, I also unhooked all the ide devices and tried another stick of ramn and same deal.
