How to find out if the problem is Software Related or Hardware Related?

You should reboot the system. When you reboot it, observe the screen very carefully because on the first screen appearing on the system, you will find a specific key that would take you to BIOS settings of your system. It may be F11, F8, or this kind of any other key depending upon the manufacturer of your system.

Promptly, press that specific key to enter BIOS settings. Let me tell you one thing that BIOS has no link with the Operating System.

So, if you notice the vertical lines are still appearing while you have entered the BIOS, it means the problem is related to the hardware only. If you don’t see vertical lines in BIOS, then it shows that it is a software issue.
