I recently turned on my computer and after 30 mins my computer froze and so I restarted it.
After that happened whenever I turn on my computer and try to boot it in normal mode the blue screen appears for a few seconds and then the computer restarts itself.
I can boot windows on safe mode and it boots normally but with the difference that I have red (pink) parallel lines all over my screen.
What could be causing this?
I have windows 7 x64.
