I have window 7 64 bit on my high end computer. the computer has been great for a few months- i really like the aero features. tonight i installed the game Batman arkam asylum. while i was benchmarking the game froze up. The windows button, control alt delete, alt tab did nothing. so i turned the pc off. when i started it up- i noticed the aero effect was gone- so i did a quick system restore. system restore then crashed and said it could not restore. i tried this twice plus i tried another restore point. i spent all night researching the problem on this site and the internet. i came up with nothing. the computer still has a registry entry for DWM but the app does not load on start up. it has disappeared from the windows services GUI. i tried to select other themes- this did not work. i tried the Aero trouble shooting app and i came up with nothing. i re ran the performance test to try to force Aero back on. I am now out of ideas!! please help!
just noticied that in the lower right hand corner of my desktop it says:
this copy of windows is not genuine??
i have a genuine version of windows and i have never seen this before!!
i just ran a sfc /sannow and there was no error detected.
ps- the system drivers
are completely up to date.
