first off update bios and clear your cmos

also check that you have all your connections correctly plugged in
also make sure you are completely updated

do you have any other gpu's to test just to rule out gpu

also run memtest

it may be a shorted reset button so check your case and unplug that connection.
it could also be a power button connection so try strating your computer using a screw driver and use the computer with out the power connection connected
go to 14:25 and watch from there to see how to do this
