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.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

yeah with what other people have said it's most likely bad or unseated RAM
have just replugged RAM and lets see if system gets frozen again.
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
Hmmm. I have also installed linux mint xfce from scratch. So far so good. It stuck only one time since this install. And its been 5 days or so i guess.
