Answer 1

Right click on desktop> properties> "settings" tab > click on "advanced"> click on "troubleshoot" tab > make sure hardware acceleration is full.

Click on start> then "run"> type "dxdiag" without quotes

A windows with directx diagnostics would open up

Click on the tab that says "Display"

make sure Direct draw, Direct 3D, AGP acceleration are all enabled. Test Direct Draw and 3D

make sure you dont have an outdated version of directx, update it.(9.0c at least)

If you have AGP/PCI express Video card, check if its compatible with the game, change settings of card( resolution, effects etc)
