I had a Gigabyte H61-m-s2p-b3 motherboard (rev 1.0) that kept rebooting after 3 seconds without getting past POST or getting to the BIOS screen. I know it's none of my other equipment because it all works fine with my brand new MSi motherboard.
Could this be a BIOS problem? does it have the symptoms of a BIOS problem?
