Hi, I have built a pc but when we get to the bios screen it says press F2. When you press it, the screen goes black and says no signal. Then it will come back on at the enter bios screen a few seconds later and it will keep on repeating this. If I leave it when it says to enter bios it will wait about 3 seconds and then just go blank and then say no signal and then show me the enter bios screen a few seconds later. I notice that when the enter Bios screen is present the keyboard light goes on but then either when I press F2 or leave it for 3 seconds the keyboard turns off when the screen goes blank but comes back on when it says enter Bios. We have achieved getting to the enter bios screen by plugging the VGA cable into the GPU to the monitor. When we plug the VGA cable into the motherboard nothing happens on the screen whatsoever. Which one should it be plugged into anyway?
Thanks,
Ben
 
Solution
Plug into GPU. Your Bios sees GPU as primary display adapter. If GPU is removed, bios will default back to integrated CPU or Motherboard display. Depending on your hardware
