In all the 3 pages, I see, only you have mentioned about different drivers failing. That includes chipset as I see in one of your threads. Can you help us understand how you determined chipset driver failed.
What is the error you are seeing in chipset case?
Can you also please run the command I have given and provide the results here. That will help us narrow down to the root cause.
I can understand this issue has consumed much of your time, apologize for that and really appreciate your efforts here.
