ATI driver help please

OK, so I seem to have a major problem. I own a Radeon 4850 manufactured by VisionTek, stock cooler, dont have it on newegg anymore. But, I decided to try driver version 8.12, and after uninstalling the old drivers and installing the new ones, i reboot. Immediately after the XP x64 boot screen, BSOD about the file "win32k.sys". (Happened about 8 times in a row) I thought this was a windows system file, but did not mess with the OS. Instead I did a safeboot, did what I thought was uninstall the old drivers, and try to go back to 8.10 drivers. When I reboot the BSOD is gone, but now I get an error saying that the MOM.implementation cant initialize. I then try to go to CCC, and it says that it cant initialize some other thing and I cant get to CCC. So I finally get to here so I could ask for some help on fixing this.

I have tried Driver Cleaner, not really sure if it did anything.

Please and Thanks for the help.

Here's what you do. Uninstall all the drivers. Add/Remove Programs "ATI- Software uninstall Utility. That will get rid of all ATI drivers. REBOOT. CANCEL any automatic driver installation. Install the new drivers. REBOOT. You shouldnt have a problem. I don't recommend updating your drivers EVERYtime they put out a new driver. Thats about every month. Just if you're doing a new install of windows or the new drivers are known to fix something you are having a problem with.

the statement above holds true if ATI, with every one of their driver release (excluding the hotfixes), dont promise performance increases with the games that you might be playing or had played before. its just tempting to do a driver update.

Yes I do ATI
