Hi Dolan A,
Since you’ve already tried the earlier troubleshooting, let’s focus on what the crash dump reports.
Open the newest dump in WinDbg, run: !analyze -v
Please post the output showing Arg1–Arg4, MODULE_NAME, IMAGE_NAME, FAILURE_BUCKET_ID, and any third-party .sys driver listed. For a 0x9F crash, this information can help identify the driver or device involved in the failed power transition.
Once you provide those details, we should have a much clearer direction for the next step.
