Please..please what should i do to solve this problem...thx in advance =(

Were you using on-board video before you got the S3? If so, make sure that the on-board video is disabled.

If you are installing the S3 to replace another video card, make sure that the old card's drivers are totally removed BEFORE you install the new card

erm wat is on-board video and how can i make the on-board video is disabled?btw how to totally removed old card's drivers?i'm blur here..sorry
