I have a problem, my PC keeps crashing when I play a game called APB:R (All points bulletin: reloaded). I have no idea why but the screen turns black and then I have to restart my computer. I've recently upgraded my graphics card and I didn't have this problem with my old one.
check the event logs and see if theres an error . did you repair install after the new card was added. you may need to if you swapped from amd to nvidia or vice versa. as this will repair the HAL which loads the default drivers for the brand of card that windows was installed with.
