Welcome to the HP Support Community!
I reviewed your post and I understand that you are facing issues with the display on the computer and getting vertical lines.
Don’t worry, I assure you I will try my best to get this sorted.
Meanwhile, I recommend you connect an external monitor to the computer check whether you are getting the display on the external monitor.
If you continue facing the issue, then boot to BIOS by tapping the F10 key on startup and check whether you are able to duplicate the issue on the BIOS screen.
Let me know how it goes and you have a great day!
