it says :

Could not determine the video card requirement for your computer. Please review the Video Card details below or use another method for your evaluation.

then when i reliase it,i download a new 1 ,dirext x 9 ..
however ,it still wont work,when i run dxdiag and go to dirextx tab,it says no problem found.
however in display tab,it says

directdraw acceleration : not available

agp texture acceleration: not available

in the notes :The system is using the generic video driver. Please install video driver provided by the hardware manufacturer.
To test DirectDraw functionality, click the "Test DirectDraw" button above.

3)warcraft3

Yes I know about the five posts rule but that is to try and ward off spammers. It was still something that I needed to know. According to your system specs you have a cheap built in graphics chip that might not be powerful enough to handle those games, at least I don't think that it is. But try this driver anyway. It says SiS AGP driver.

It looks like that chip barely meets the requirements so if the driver doesn't work you might have to get a graphics card. Thats all I know to tell you. Lets see if someone else chimes it.
