Well... some other possiblities i could think of...
Did your computer match the minimum requirements for the game? In terms of processor speed, hard disk space and etc...?
Check your graphic card drivers. You might using an old driver that might be conflicting with your OS or some other hardware. If it's so, visit ur graphic card webby and download the latest.
Check if the game you are running is supported by the graphic card. If it's not, visit ur graphic card webby and download the latest, or wait for a patch for the game to correct the bug.
Dat's all i can think of now... Btw, what's the game? |
