Hello everybody, it's since 2 years ago I have this problem... I'm running well Windows 7 x64 on my first pc, i2500k and hd6970... I have a second pc, an old Acer Aspire E500, desktop, with a pentium D dual core 2,8ghz processor. I changed its video card buying and ATI HD4670... I'm running well videos and other things... but, since I installed windows 7, I'm having a problem: after 1,2 hours, randomly, the Aero theme crashes.. and then it seems that the video drivers
crashes because every window I try to move on the screen, it laggs... when it crashes for 1,2,3 times, it could be recovered using "net stop uxsms" and then "net start uxsms" in the command prompt... (but the most of the times it is auto-restored by the system... then, even if I try to restart the service, it crashes after 5-10 seconds... what's happening?
I tried to reinstall my video drivers, but I tried updating drivers since 2 years ago... so I think they're not the problem.. thank you
