This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: atikmdag.sys (ATI Radeon Kernel Mode Driver, Advanced Micro Devices, Inc.). Google query: Advanced Micro Devices, Inc.

I have this exact same problem! Was using 13.4, upgraded to 13.10 Beta to try it out, attempted to revert to 13.4 ... and no matter what I do I am unable to get my 5970 working again. Dumps say atimdag.sys is the root cause. I have used Drive Sweeper as well as the AMD CleanUp Utility without success. Trying to install any flavor of Catalyst 13.x gives BSOD, and 12.x installs incorrectly and CCC won't run.Am able to fall back to an older ATI 4870 x2 without problems running the final release for the 4000 series, and can switch over to an NVidia 285, but time and again when I try once more with the 5970 I can not get it working again.Any all advice / suggestions welcomed!!!
Un-install CCC through Control Panel, then go to Device Manager and un-install Display Graphic Driver. Go to Action menu select Hardware scan. You should be back to Windows Default driver now. From here install CCC for 13.4, and hopefully you are back in business.
@WMudrockJr - thanks for the suggestion, but didn't work.Here is what has finally worked for me: uninstalled and cleaned system of all drivers, installed 4870 x2, booted into Windows which loaded default drivers, installed the special Catalyst 13.1 that is specifically for the 4000 / 3000 / 2000 series cards, rebooted into Windows, uninstalled current drivers via Catalyst Install Manager, uninstalled graphics card via Device Manager and specifically checked the box to delete current drivers, shutdown system, installed 5970, booted into Safe Mode, ran Drive Sweeper, ran AMD Catalyst Un-Install Utility, ran Regedit and deleted all AMD / ATI entries (which I could safely do since this is an Intel desktop), rebooted into Windows which used default drivers, and then installed Catalyst 13.1 for the 5000 series. Working fine. At some point will probably install a more recent version of Catalyst, but happy to be operational again.
