My PC is not outputting any video, either through the motherboard or the GPU outputs, to my monitor or a TV, Displayport or HDMI. It is definitely booting fine, as I can hear the windows login screen sound, but I cannot get any video output, not even in the BIOS.

The problem occured when I tried to change my monitor's refresh rate from 144hz to 60hz in the hopes of fixing a visual bug (which I've encountered many times before, I usually just restart to fix it.). When I boot, my monitor wakes from sleep, and my TV autoswitches to the HDMI input, as thought they are getting a signal, but on both a "No signal" error is displayed.

My GPU is a 970, if that matters.what steps can I go through to try to fix this?yes, I've tried restarting multiple times.
