Installed Catalyst 15.7.1 for Windows 10 64-bit and now cannot boot except in safe without getting; "Driver IRQL not less than or equal (CHDRVR01.SYS)" Catalyst says "cannot run detection" in safe mode and halts
Finally got it to work after trying various things with no effect. I got into Safe Mode and deleted CHDRVR01.SYS (actually renamed it). I was able to get into Windows and run the Catalyst installer completely. Everything seems to be stable and running as intended now.
No System specs., so who knows?
