So today i recieved all the parts for my brothers pc build and when i assembled everything on the motherboard box and pressed the power button the power light stays on, the debug code light flashes on then off, and my m-bios and b-bios lights are flashing. All the fans turn on, gpu fans are spinning but i have no output going to the monitor.
I'm lost, i've tried changing the bios, using a single stick of ram, switching the ram slots, removing the c-mos battery. Any ideas?
specs of the pc are
i5-3570k
gigabyte ud5h
corsair vengeance ddr3 8gb
noctua nh-d14
gigabyte gtx 670
samsung 830m ssd (i think. cant remmber the exact model)
corsair hx650 psu
