I left my machine running last night, and when I woke up this morning, it had powered off... now, when I try to boot the thing, I immediately get a mid-length beep, repeated every few seconds, and no display (can't even make it to BIOS to see what went wrong). Turning to the board's manual is useless, since there's no section relating to errors from the board (endless optimism by Shuttle, eh?). Has anyone run across this before? I'd rather not have to go through and test every component in the box, but that's what the afternoon's shaping up to be if I can't find a listing of what the hell the beeping means about failure in the POST. Thanks!
