Well I had my laptop for 2 months when I dicided to send it in as driver updates wern't Fixing the flickering.
you tube was ok didn't see any flicker when wwatching clips/video, was only ion games that it occured
even once hat weren't graphis intennsive, like sins of the solar Empire/world of goo(steam game) and scorched eearth 3D all had the flicker.
Anyway me laptop should be back in me hands by friday, unless the parts turn up before the send it back(which i highly dought will happen)
at least my temp fix will reduce the flickeriing to a tolerable level.
