I have a clevo p150sm, 8gb ram, intel 4600+amd radeon hd8970m (with 15.4 beta drivers installed), windows 8.1 64bit and I'm trying to update the drivers of the ati.
I restarted the laptop in safe mode and uninstall the old ones with driver uninstall then restarted again in normal mode and install the new beta 15.11 but I got an error during the installation before finishing it: I got a blue screen with this error "DRIVER_IRQL_NOT_LESS_OR_EQUAL (amdkmpfd.sys)", then the pc restarted automatically.
I tried this process again with the 15.7.1 but still the same problem.
So i had to go back to the old drivers 15.4 beta drivers, that looks like are the only drivers that give me no error.
Do you know what can cause this problem and how could I solve it?
