Reasons behind “Vertical Lines on Screen” Error
The vertical lines on the monitor appear from top to bottom on the screen. You can usually see the multi-colored or blue vertical lines on the screen. Mostly the issue is due to hardware failure or graphics card problem. Damage in the screen can also be the culprit here. Mostly the error may be due to the compatibility issue of the software or may be a hardware problem. So, before applying any technique, it is very important to know that whether it is a hardware problem or software issue. You should reboot the system.

If you don’t see vertical lines in BIOS, then it shows that it is a software issue.
