This is really bugging me! Having recently built a new computer and installed Windows 7 I have noticed the Aero functions is not working, also the Peek at desktop is checked but greyed out. I have a Windows Experience score of 5. I have tried tthe Aero trouble shooted and it tells me the Desktop Windows Manager is disabled, but if I look in services it is running! Also when I look at adjusting the visual effects in the performance menu I only have 15 check boxes and enable Aero isnt there?? This is driving me insane, I have updated my drivers. I an running a AMD Athlon II X3 435 Asus M4A77T Motherboard Asus ATI Radeon HD 4650 2GB ram Please help!
