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.

      that’s good then! i had this same issue (randomly freezing after turning it om for some time) though new RAM ended up fixing it
