is it hooked up to a screen? how far do u get? bios? XP screen?
yea that psu is pretty (insert bad word here cause i cant think of any)ty
though that is thier top line pretty much
3 seconds would be about the time it would take for one of those temp programs(shut down ur cpu if its too hot)
i couldnt imagine any comp running for 1 single second and fully shutting off by itself, if in the rare event it did that probaly means it just fried everythign in ur system
but im no expert this is just guesses
