Desktop Window Manager gets disabled?

I know this is way off-topic but the Desktop Window Manager service keeps getting disabled and when i change themes it won’t let me go back to aero unless i run the troubleshooter and later the Desktop Window Manager gets disabled again. the troubleshooter enables it but like i said later on it becomes disabled again. Any Windows 7 users on avast web forum had this problem once in the past if yes how did you fix it?

See if this answers your question:

Nope it didn’t I have a good Graphics card cause Aero has never did this before to this week.
