Hi, I was running a genuine copy of Vista Business x64 with no problems, all drivers installed etc. I then downloaded and installed SP1 RTM and again no problems until my screen flashed and then suddenly aero was disabled; I am stuck to "basic", there are no options on the properties to access aero and only classic and basic etc are available. Reinstalled catalyst 8.1, used driver cleaner and still no luck, uninstalled SP1, installed cat 8.1 and still no luck. It isn't reduced functionality or anything like that, everything is fine apart from aero. Has anyone had this problem, and if so maybe a solution to get this fixed. Thanks!
