Screen goes blank after changing BIOS settings/

I don't know how long this has been happening, a few weeks at least, but whenever I change a setting in my BIOS (and save & exit), my screen goes blank and my monitor goes into standby. Any suggestions to fix this?

 

Blank Screen

Hi Virginia,

Conflicts with third-party software and outdated graphic drivers are common contributors to the black screen issue that you're having. To isolate the said issue, we'd like to ask a few questions:

• Are you getting any error messages before getting a blank screen?
• Are you experiencing this when using a particular app?
• Were there any changes made on your computer settings prior to this issue?

Meanwhile, we suggest that you refer to this
article which talks about the steps you can take to resolve blank screen errors.

We'll wait for your response and assist you accordingly.

What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
