BFGminer running for 2 months without issues. Updated to AMD drivers 13.4 today. Now it's crashing on startup everytime. Using AMD HD6850 and Windows 7 x64 SP1 + all windows updates.

Command line: --gpu-threads 1 --queue 0 --intensity=d --gpu-dyninterval 16 --failover-only

I deleted the precompiled kernel and it's not making a new one. There's nothing written to the console.

Both 3.0.2 and 2.10.8 crash in the same manner.

EDIT:

Fixed. I am leaving this here for those who end up having my issue.

-Uninstall all ATI software.
-Restart.
-Create a batch file with the following and run it:

@C:
@cd C:\Windows\System32
del SlotMaximizerAg.dll
del SlotMaximizerBe.dll
del amdocl64.dll
del OpenCL.dll
del OpenVideo64.dll
del OVDecode64.dll
@Cd C:\Windows\SysWOW64
del SlotMaximizerAg.dll
Del SlotMaximizerBe.dll
del amdocl.dll
del OpenCL.dll
del OpenVideo.dll
del OVDecode.dll
@rmdir C:\ProgramData\AMD\KDB /S /Q

-Reinstall ATI 13.1 drivers.
