This question already has an answer here:

I just reinstalled windows 7 on my computer, and aero is not working anymore. I did not change any hardware or drivers, and aero worked before reinstalling windows.

I am using a nVidia GeForce GTX 560 for the primary display and Intel HD 2000 for the secondary display, and I have a Experience Index of 7.5.

I already tried net stop uxsms - net start uxsms as suggested in many of the links google provides, but it still does not work.

What else could I do to enable aero again?

Edit:

I just found this in the event viewer:

The Desktop Window Manager did not start because an analysis of the hardware and configuration indicated that it would perform poorly.

Also, starting without graphics card works. But I still want to use the card, so this is not a solution for me.

@techie007: a reboot doesn't fix it for me, so I guess it is a different problem (it didn't work since reinstalling windows). I already tried the solutions in your second link (fix-it, msconfig, experience index) but it didn't solve my problem. –  pascalhein Jun 1 '13 at 15:11

Try to rerun the Windows performance index test, maybe it thinks the graphics card is too weak. Also, does it actually show the GTX560 in Device Manager (or maybe just a plain VGA card, due to lack of or broken drivers)

the device manager shows Intel(R) HD Graphics and NVIDIA GeForce GTX 560. after rerunning the performance index, it still shows 7.5, and aero still does not work. –  pascalhein Jun 1 '13 at 16:21
