I bought my Radeon HD5850 card around New years 2009/2010. Installed from disk and updated to latest driver. Everythin worked and I was happy (oh the good old days). Today (6 hours ago) I upgraded to latest version (Filename: 10-2_xp32_dd_ccc_wdm_enu) and...it screws me three different ways. Why oh Why must I always feel a need to use latest drivers... During install I get a CLI.Implementation fail. After reboot I get MoM.Dependencies fail and CANNOT access my catalyst Control system. So I can't switch screens or redo my settings for certain games. It seems this problem has dogged ATI cards for about 4 YEARS! - has nobody at ATI or AMD pulled their finger out and fixed it?. I have .Net 2.0 SP2, .Net 3.0 SP2 and .Net 3.5 SP1 (incl hotfix)installed. I have tried complete package and just the CCC driver versions. I even did a system restore which just said no changes were made and it sucks to be you. I'm not a computer Wizkid, I can assemble them and do setup and basic maintenance/tweaks on WinXP. I'm only user on system (lists account as admin) and guest account is Off (system was completely reinstalled on Jan 3rd 2010. Worked flawless until 6 hours ago). I've tried all fixes I could find exept one requiering mass edits of the registration DB, something I am not at all comfortable doing. It's been 6 hours of fighting with it, I can't anymore. I'm turning here for help cause you people have never failed me before. Now I'm gonna go get drunk and maybe have a good cry (in a manly punch the wall kinda way)...
Download the older driver and use 7 zip to extract it to a folder. Fully uninstall the CCC using the control panel's add/remove programs icon. (don't restart if it asks you) Then goto device manager and open the properties for the video card. (if it is not there, then restart and do this) Manualy guide it to the folder where you extracted the old driver, and force it to install that driver. Repeat last 2 steps for the HDMI audio device.
Worked. 10.1 running smoothly now. Thank you very much for validating my faith in afterdawns community. Here's to hoping 10.3 won't be the same piece of.....
I wish ATI would test their drivers before releasing them. As it is, they will not even remove defective drivers from their website when they are shown to be defective, and they even continue to recomend the defective driver over the old one, advising people to disable half of the features just to make it work well enough to use the desktop.
