Screen flickering and Firefox not responding

Hi all

Windows 7 was great when I first installed it, but now I cant use it at all, due to the huge flickering problem, firefox keeps going into "not responding" for a couple of seconds every time I click on some thing, and the same to many of the apps I use like Illustrator, its now so bad, I can no longer work on windows 7, so will I be upgrading to windows 8 when it finally comes to the masses, I don't think so, at present I have gone back to windows XP, this for me is the most stable windows ever, fast and never let me down.

have you found a solution to this?
