Do graphics and text appear grainy or chunky? Does it look as though application windows no longer fit on screen in the way you're used to? A resolution or device mix-up can wreak this kind of havoc. If you can read the screen well enough, review the graphics resolution and other settings by right-clicking the Windows desktop, clicking Properties, and selecting the Settings tab. Check the Screen Resolution slider bar and the graphics card model to confirm that they are as expected. When this kind of problem occurs in a game, driver software could be at fault. Go to the vendor's Web site for the most recent driver. Sometimes, an older, more stable driver may produce better results than the latest version.You might also check for a patch to the game.
