Graphics card and Battlefield 2142 error

Hey guys, ive been running a lot of games perfectly on my system and they are all working great, but i have encountered a recurring problem in BattleField 2142. i can play the game for upto 2 hours with no probles but then the game will crash and 5 minutes later i get a blue screen of death saying there is an error with NV4_disp and it is stuck in an infinate loop etc. any solutions guys? i have completley uninstalled the drivers and re-installed them already a few times and it seems not to change anything, thanks

This looks like it might help:
