Hi Joe_Ace_22,
I am Dave, I will help you with this.

Boot your PC into BIOS and leave it in there to test if the problem exists in BIOS, if it does, then you have a hardware problem on your monitor and you will need to bring it to the PC repair shop.

If that problem does not appear in BIOS:
Open Device Manager (accessible by right clicking your Start Button)
Expand the Display Adapters Section
Right click your video card and choose Properties
On the Driver Tab, choose 'Roll back Driver'
Restart your PC once done.
If that option is not available or does not resolve the issue, go to the support page for your device on the manufacturers website, then download and install the video driver they recommend, it may well be an older version to the one you are currently running
