Hi @Colin2552,

Welcome to the HP Support Community. 

I'd like to help!

To be able to answer you effectively, we need some information.

Have you checked in Bios to see if it does the same? If yes, this could be a display issue and might need service. 

You may refer to this document  select the option Image on the screen flickers, has lines or distorted colors

Hope this helps! Keep me posted for further assistance.
