First I will suggest you to upgrade your graphic card to play high quality games
- Or there may be your graphic drivers are out of date so I will suggest you to restart your computer and then press and hold F8 keys until you get Advanced Options menu screen.Use the arrow key to highlight Safe Mode, and then press Enter, your computer will boot automatically to safe mode.
- After that go the site of your system manufacture. Once there enter the model number of the system then request driver (usually found in the web site's "Support Section"). There you should be able to find all the drivers for your model
hopefully you will get better results
