Provide a copy of the Full OC folder, as what you have provided leaves too many variables unknown.
Where did you get the SSDT's in your ACPI folder? Do you need all of them with your Coffee Lake system?
Nearly all Coffee Lake systems I have dealt with only require these four SSDT's:
- SSDT-AWAC.aml
- SSDT-EC-USBX.aml
- SSDT-PLUG.aml
- SSDT-PMC.aml
A copy of these four CFL SSDT's are attached below.
Coffee Lake systems do not usually require the SSDT-HPET.aml or the SSDT-SBUS-MCHC.aml. I would suggest you remove them and replace the others with the ones provided below.
