ATI Radeon HD 4800 Series problem on Windows 7

I had been running Windows 7 on my machine. Recently i had installed the latest drivers for the ATI Radeon Hd 4800 graphic card on my system. Now the problem is that when i use windows 7 I get a corrupted screen. I tried to install ATI Catalyst driver (which was O.K. with previous Sapphire (X850) card) from console, but it did not help. The problem starts when windows downloads drivers and even when I install AMD ones it still refuses to show a clear screen. I have had this problem even from the windows 7 setup/installation. Can any one tell me that why i'm having ATI Radeon HD 4800 Series problem on Windows 7? Any one has any idea about it? Kindly help me to get rid of the above issue. Thanks.

It sounds like your graphics card driver is somehow corrupt on your PC. Have you tried the package Envyng-gtk from Synaptic Package Manager? Try uninstalling the AMD software suite completely, reboot, download the latest driver suite (v9.11) from your HD4850 manufacturer or AMD directly and install it again.

The compatibility problem with Vista/7 is called (superior) PowerPlay. There's nothing wrong with the cards but the drivers. Did you perform a clean install of Windows 7 RTM? Did you try boot into safe mode and see if your screen shows up? What video interface are you using btw? DVI, HDMI, or DVI-DB15 converter? Sometimes they can't handle the changing of the memory clock speed.

You cannot explicity turn off the 3200 via bios but it does not run if don't plug things into it. Turning off Compiz effects appears to be a common work around for those that get the proprietary driver working but experience flicker during video playback.It works fine in Safe mode but I have been told that is no indicator. Ensure the cards are not overheating, and if you are overclocking stop. The most common reason TDR goes off is overheating or an unstable overclock.

I try to Install the New Ati drivers
but when I chk Version in
9.11 it shows 8.67
9.12 it shows 8.63

Why is that :(
I did uninstall
Boot in safe mod
& run Driver sweeper

then restart & Install
then Mod & then Install drivres

am i missing something :(

Please be sure that you remove every small changes made to the system before uninstalling the previous version of the driver & installing the new one. Please do the installation run as admin. You can use Driver Cleaner Pro too. You can also try beta version of ati catalyst control center special for windows 7. Try running Driver Sweeper to clean the old drivers before attempting to install the latest package?

Did you install any kind of video drivers with ATT included? Could also be an issue with the bridge chip and your chipset. You should always uninstall your current display drivers before installing new display drivers. If you install new drivers over the old ones, parts of the old drivers can be left around and cause problems.

Yes I did run Driver Sweeper

Where can I get -
beta version of ati catalyst control center special for windows 7

The drivers for ATI Radeon 4800 series which are supported in Windows 7 are not available yet. The Aero function in Windows 7 is not supported by the ATI cards and hence the card is not functioning properly. Remove the catalyst controller and then download and install the ATI manger to configure the card properly to work in Windows 7.
