BF2S Forums now this is seriously pissing me off.

Basically whenever I play BF2 my graphics just fuck up, large area's of the screen will turn yellow and sometimes the game will stutter, its impossible to play with. I ran prime95 and did torture tests on both my ram and my processor after several hours both came out clean. I guessed it was my graphics card that was to fault so i RMA's it after a week of not having a graphics card I got the new one, same model different batch. I put it in and fired up BF2 as the drivers were all up to date from my previous one. I got the same problems, as always it turns yellow, stutters and freezes up giving me a black screen when i try to quit or at random times. I don't want to get another RMA if I'm not sure that its the card thats at fault, last time ebuyer said they tested it and it was faulty but this is a brand new card and I want to know what it is thats wrong. Oh and the problems are actually much worse on the games default settings (mostly medium) than when I set it to its highest and its only BF2 that fucks up I think I've not played anything else graphically taxing for a while but when i played company of heroes and oblivion on it it was fine. I've reinstalles BF2 and repatched before now and I've tried removing and reinstalling the drivers for my graphics. Oh and when I first got this pc in march it was fine.

please help before I end up destroying something with something else thats heavy (not sure yet but I'm thinking about the sledgehammer in the shed)
