I installed C&C3 on my Vista Home Premium system, patched it to 105, and it
runs fine. Have you tried a reinstall of the game, but, I suspect that your
problem is that the onboard graphics just can't handle it. Maybe you should
boot from your Vista DVD and run a repair? You do not list other specs of
your machine, ie: RAM, CPU. In my system I have a Radeon HD2900, 8GB 800mhz
RAM, and a lowly E2140 CPU (overclocked to 2.8Ghz), so I reckon it isn't a
CPU problem. In the "Games" window, what are the required machine specs
compared to what it says yours are? Have you run the Performance Information
and Tools utility available through contol panel to determine the ratings?
Hope this helps.
