Welcome to the forum anocin. Please post often as we love a challenge.


Are you over clocking the CPU? This could have an effect on the AGP slot as the same bus clock could be used for both the CPU and the AGP timing. If you are try returning to the factory default setting.

You may have a memory problem. If your 256 meg is in 2 128 meg sticks try removing one and testing your system again. If the problem is still there reinstall the stick that you had out and pull the other stick and test again.

If neither proves to be the problem please post again with more information about your conditions and system.
