Changed Hz from 60 to 75, black screen? Display: No signal

I had everything working and I went to try to change the hz from 60 to 75 becuase my monitor supports it. Well bad decision. I can't seem to get it to boot and show the screen. All it does is show a black screen and my monitor say no connection and the monitor will turn off. When I boot in save mode I can get to the login screen but once I log in, it'll go to a black screen. I'm currently running a 1080 ti with Nvidia drivers. Have a dual boot system, anyway to fix this?
