Hi sHAve31, and welcome. Your machine will do fine with Vista. And, actually, I think it should do fine with Aero. The 945 is supposed to support Vista. I would check this issue out carefully on the Intel site, and look for a Vista related driver for the 945. Also, try the Vista Upgrade Advisor on your machine:
