I upgraded my graphics card a few months ago to a Geforce fx 5500 and have been having problems with strange shapes flickering over the screen. This can usually be sorted out by minimising the game to windows and then maximing a few times. After that all games run fine until I restart my computer and then it happens again. This did not happen with my old graphics card.
Here is a screenshot of the problem:
Is the problem my graphics card or is it a driver issue. I downloaded the latest nvidia drivers but this did not solve the issue.
Thanks for the help.
