I recently updated my GPU from a Nvidia 780ti to a Nvidia Windforce G1 1080. My monitors are now receiving no signal from either GPU or Motherboard HDMI ports and DP. I have put the 780ti back into the computer but still no signal and I have also just removed the GPU but nothing is giving my monitors a display. I have check that all components are properly powered.

Try resetting your cmos (should be a jumper on the motherboard, or a button, or you can just remove the battery and unplug the power for a few minutes).

Check all the power cables to the motherboard, in case one has been disturbed.

Theres no good reason why a new gpu would cause the old one not to work.
