Had a wierd issue earlier while i was browsing, the screen went black out of nowhere but the monitor wasn't on standby. i reset the computer numerous times and it shows the SABERTOOTH X58 Logo for about 1 second and goes black, as before the monitor doesn't go to standby either. tried pulling the CMOS battery and changing the GPU and no luck. everything else powers on fine however. any suggestions? and my CPU was overclocked to 4GHZ (i7 930)
