I have a he pavilion laptop and the display malfunctions,but only from time to time.
Sometimes it'a fine and sometimes it malfunctions and many lines and blurry images.

Sometimes it went entirely black and sometimes I could see the windows 8 express bar and select things but the screen had many lines with different colours

The thing is that it becomes completely normal after a couple of days.
What is wrong with my laptop?
