Randomly on my laptop screen this appears and debian just freezes. Sometimes these vertical lines don’t appear and system freezes anyway. Its just random. How do i identify if this is hardware or software issue? and then how to identify exact piece of hardware or software causing this problem.

      May just be bad RAM as well on a 12 year old machine. Should be cheapish to replace. Try running a memtest
