I was on win8 when it suddenly crashed I had to reboot system. After reboot, win won't start. I booted linux (kubuntu 14.04) and saw these thick red lines (which chage color depending on background) on my monitor which is via VGA connected to my laptop, while laptop screen is pitch black and isn't even recognized by the system.
How can i identify problem source and how to solve it ?
