Monitor "No signal" when booting up

Aquatics
Go to solution Solved by Aquatics,

Thank you everyone for the help, o figured it out, had to keep restarting my PC until I could restart PC from an old safe point, I lost a couple things, but not that bad I'll just redownload them 

My windows was all fine until today when I was changing my resolution, now it boots into bios just fine but when it starts up windows it just says no signal. I'm not sure whats wrong.

you dont have a problem with the resolution in the bios , the problem is the resolution in windows. your bios settings don't alter settings within operating systems.

How can I boot into safe mode? I can't even go into windows as the monitor shows no signal

I tried it and it went into bios safe mode, is this what's supposed to happen? 

 

What??

There is no "BIOS Safe Mode" ... there is only BIOS.

BIOS is BEFORE Windows, BEFORE drivers.

You can go into BIOS without a HDD / SSD plugged in.

 

Safe Mode is a Windows / Operating System thing.

 

Read through this CAREFUL.

It lists multiple ways to get into Safe Mode.

https://www.digitalcitizen.life/4-ways-boot-safe-mode-windows-10/

 

Method #1) Getting into Safe Mode if you can make it into the login screen.

Method #2) You cannot make it into the login screen, and you force Windows to trigger automatic repair, which then gives you the Safe Mode option

Method #3)  Use a Windows 10 install USB/media and going through Command Prompt.

 

If Method #1 doesn't work, most of the time, Method #2 should get you there.

Unless your Windows install is completely goof'd, Method #3 is usually needed...
