Any clue please.Thanks AM

The graphic artifacts that you dealing with, are probably because of heating problems.

If it happens right after you turn on your laptop (when his cold), and the problem still occur - I assume that your video card is damaged.

If you got warranty - I suggest to use it as soon as possible.

Sounds like the cable is either lose or the monitor is going on you. If you can find a manual online to take it apart you can try to check that the cable is tight and if it is you will need to buy a new LCD screen.
