I appreciate for all the trouble shooting steps tried. You have tried almost all the steps which should have resolved the issue. Since the issue is persisting, I recommend you to run diagnostics on the hardware components of the system. Try running the test once the system is out of sleep mode and system is overheating. Please refer to the following link for instructions:
