This is my first time on these forums, and if this has already been addressed I am sorry, I searched through the forums, but did not find anything relevant and do not have hours to sift through threads.
Basically, I am running Vista 64, with two Sapphire Radeon HD 4850's running in crossfire. I built the rig in July and had no problems setting it up and getting crossfire to work properly with the 8.7 drivers, but newer drivers do not work.
With the 8.7 drivers installed it works fine, however, when I try to update to 8.8, 8.9, 8.10 or the 8.10 FC2 Hotfix (which is most important to me now) I get an error message from CCC on boot that it could not load because either no graphics drivers were installed or there was a problem loading the drivers or the hardware (cant remember the exact message). When looking at both of the graphics cards through device manager, both are listed with an exclamation mark, and the error is listed as Code 43, there is a problem and the the drivers could not be loaded.
I have gone through and ran driver cleaners in safe mode, tried installing on top of other drivers, doing fresh installs, uninstalling the cards through device manager and letting windows pick them up.
So far the most success I have had was to clean the drivers, do a fresh install of the hotfix, boot into windows, uninstall both cards, reboot and let windows install. I was able to get the new CCC working just fine, but when I checked the driver versions in device manager they were both old, so this really doesnt help me at all.
In addition, I have taken both video cards out of my system and I am able to install the drivers just fine for each card individually, but when the second card is installed, I first get the code 43 error on the second card, then on reboot, on both.
Please help me! I really want to get these new drivers working, especially the FC2 hotfix as it comes out really soon. ATI support has only told me what I have told you above and has not contacted me back for two days, so I dont know what to do, any help would be greatly appreciated.
