Some months ago I have my windows 7 aero effect enabled, and there is no problem. But now I have problems when using aero effect (I mean aero theme).
First when using aero theme, minimizing windows take a long time, windows halt for some seconds like 7 or 10.
The second problem is after minimizing windows(sometimes), my windows automatically change into classic theme and show me a message saying "The memory is not enough, to boost performance switched to classic theme", even though I have 4 GB ram installed and no extensive CPU usage.
This happen no matter whether applications are opened or not. But I created a new user account and found out that the new account is working perfectly well in aero theme. I don't know why. And in that new account ALL SHORTCUTS didn't load the graphics, just the white spaces. Please give me solutions.
