Im not sure if this has been posted yet for CLoD, I found this Thread
http://forum.1cpublishing.eu/showthread.php?t=6711 while researching fix for back to back crashes after installing Beta Catalyst Drivers. I opened C:\Windows\System32, located atidxx64.dll , then removed it to a an empty folder on desktop. Launched my game and havnt crashed since I removed the 64.dll. So give it a try. Report back if you will, fixed or not. Thanks.
