several graphic card issues

[c0oKi3]

I am using a 9800xt. Whenever I play 3D games, artifacts would pop up once in a while. Also, I cant seem to set its AGP speed from smartgart. The option of enabling and disabling fast write is also greyed out. Just recently, I can no longer use the DVI cable to attach my montior. It would just say that no connection is available. Anyone have any solution for any of these problems?
