so, my friend built his pc, and he couldn't get it working. so i went over and had a look.
the pc is not outputting any signal to the monitor, so we've tested several things:
the GPU- we put the GPU in another build, and it works fine
we've also put another GPU in the not working build, and again we had no output.
all cables are plugged in, we've tried everything from HDMI to mini-display port, to VGA nothing worked...
all fans work, no beeps from the motherboard speaker...
so, we've come to the conclusion that something is wrong with the MOBO...
what do you think?
GPU= AMD HD7950
MOBO= AsRock 970 extreme3
