Unhandled Exception, cannot run virtually any game, WTF?

[D22]

Almost no game will run on my computer which is a P4 @ 3.15 with a geforce 4 ti 4600 video card. Rise of Nations, Empire Earth 2, Rome: TW, etc. etc, all end with errors like "unhandled exceptions" followed by weird debugging code, and "Bhg rts run time error
Vertex batch too large
Safe to ignore: unlikely"

Cannot find answers anywhere. Already tried reinstalling drivers...help!

Reinstall the latest DirectX and video drivers. Has your video card ever been able to run those games?

Exactly HOW did you go about installing the drivers?
