    M17xR2 Driver/BIOS/Crossfire woes

    I recently discovered that my crossfire was no longer working, and Dell sent me a set of new cards. That didn't resolve the issue.

    So I decided to try to go back to baseline on my drivers, as I was running the X31.4 bios, and had the latest catalyst drivers installed. I rolled back to the A10 bios, and then tried to uninstall the catalyst drivers and reinstalled the 8.763 drivers from Dell, but it was obvious there was still some lingering foo from the catalyst drivers (the control center showed the 8.763 version of the driver, but said I was running catalyst 11.5). So I used DriverSweeper to totally clean all the ATI drivers out, and reinstalled 8.763.

    Now I'm getting that MOM.Implementation error (and can't get into the CCC), and nothing I do seems to get rid of it. I've tried uninstalling .Net 4 and the drivers, and reinstalling them, tried turning off & on the windows 7 built-in .net 3.5.1, all to no avail.

    I don't have a restore point far back enough to fix this, and I've been told in no uncertain terms that I'm not going to do a factory restore again (it's my wife's laptop). Everything I've looked up to resolve this keeps pointing back to uninstalling/reinstalling .Net and the drivers in order, but that isn't helping at all. Anybody have any idea what I can do?

    I should probably mention that I've seen that mom.implementation error when installing the latest catalyst drivers, and doing the .net/driver uninstall reinstall business DID work then. I'm guessing the older catalyst uses an older version of .Net than 4 or 3.5.1, and the 3.5.1 Windows Feature isn't properly providing compatibility for < 3.5.1.
