Hmm. . . You may have knocked something loose then. Go back and carefully recheck all connections, cables, etc. Reseat all peripherals such as vid card, memory, etc.
already did that...lol i have the worst luck with these problems...and seagate tech support isnt open till wednesday...it worked fine until i installed the software and restarted...could it be that the software is at fault?
boot loader doesn't effect POST, you need to reseat your RAM and video card first and foremost. try booting with only 1 stick of ram and try reseating the cpu as well. something isn't plugged into the motherboard all the way.
