I'm having a very basic problem with the ATI Catalyst control center; I can't get it to work. When I got the computer it worked fine, but over Thanksgiving when I let my older brother use my computer, it stopped working while I was asleep, so I don't really know what happened. He was just supposed to be playing Spore, so I don't know what happened to it. I have (or am supposed to have) the ATI Catalyst Control Center installed for my graphics; I have an ATI Radeon HD 3200 Graphics listed under my display adapters (which is my "video card"). I have installed and updated the latest version of the Control Center, but on my "Windows Experience" I have "Desktop Performance for Windows Aero" where it used to say "Catalyst Control Center" when I originally got the computer. I'm trying to switch the Windows Aero back to the Control Center, but don't know how to do that. The only computer program that won't run for me the way my computer is now is Spore; my older stuff mostly works fine, which is why it took me so long to find the problem. I'm running Windows Vista Home Premium; I hate Vista, but it's all there was at the store. Can anyone help me? The five threads that popped up aren't related. I'm not very computer savvy so please give specific instructions (especially where to find things). Thank you for your help.
