Recently i update my graphics card and install a new one Sapphire HD 4670 1gb ddr3 the problem is after installing the driver
the aero disabled itself and when i troubleshoot the problem a error message comes windows desktop manager is disabled even i tried the latest driver but nothing help. I update my system drivers
like bios,chipset,sound and others but nothing seems to work. I am using Windows 7 ultimate x32bit I really wanted to use this card under Windows 7 but because of this problem i couldn't.
