error 0x9f, ACPI - will BIOS update fix?

Try reinstalling the graphics drivers. OpenCL is from your graphics drivers. Try this, it is from Sevenforums, but do as much of it as you can. Only install the Graphics drivers and PhysX drivers. Do Not install the GeForce Experience.

Okay, now I'm totally confused. I thought you were referring to something in sevenforums?

OK, the above is a link to download drivers this is a link to the tutorial. You will not be able to do everything in 10, but do what you can and try to just install the Graphics driver and PhysX Driver.
