I recently installed a korean game called SuddenAttack (FPS).
When i started a game it would work perfectly fine until it freezes and 3 minutes later a box will come up and say
Vtdisp Display Driver Has Stopped Responding.
Save your work and restart your computer.
is there any way to fix this problem without getting a new video card cause it plays the game perfectly then all of a sudden it freezes.

Try updating your video driver, rather than the card itself.

how do you update the driver because i updated the card itself but never the driver

IIRC, you just google 'update *insert video card here* driver' and find a legitimate updater. Or you can use windows' updater, I forget how to get to it though.

k thxs ill see if it works or not

this is annoying....
I played 2 games without problems, the 3rd game i played just froze on me and the same message came up and i had to reboot my comp again.
