Question Gaming pc black screens for ~3 seconds

[ethanrae]

I recently got a new GPU, but have been having this issue while gaming. I tried reinstalling amd drivers, cleaning nvidia drivers from my pc completely, moving the plugs from my GPU to my PSU, messing with the hz on my monitor, turned on and off freesync and enhanced sync, etc. Sorry about the amount of information, but I'm not sure what you need.
