Windows 7: Windows aero doesn't work

Hi

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.

You can start the desktop windows management by going to Start>Run>services.msc
Locate the Window Manager Session Manager and start the service
Re-enable Aero
If it is disabled, set it to start automatically

I have already done that plenty of time

Try uninstalling the drivers you just installed. Then reboot, and let Windows automatically find and install drivers.

Windows Install Ati radeon hd 4600 series drivers itself. But the problem is. It doesn't work

You get the same results with both drivers?

yes

Try downloading drivers from here: SAPPHIRE- HOME

Select your card and OS, and download the drivers it brings up.

dude i have already installed the drivers from the official site. I just want to tell you that when i install other driver. Like manually install the driver from device manager and choose update my driver and have choose from the list and select the asus eah4670 driver version 8/8/2008 it's work but the problem is i cannot play to the latest game i mean game performance are really annoying infact we cannot choose other company driver for our device(The card manufacturer is Sapphire but why it accept other driver)

The card will accept ATI drivers, but Sapphire drivers will hopefully work better.

In case you don't know this already, the GPU was manufactured by ATI. The card was assembled by Sapphire.
