BSOD Lenovo Yoga S1 only when A/C plugged in, REGISTRY_ERR

I have been troubleshooting all weekend while I await the arrival of the recovery CD that Lenovo support is sending per the latest support call. The BSODs only started after I received my Yoga back from Lenovo repair depot. I then requested in-home repair at which time a technician replaced the system mother board, after which we quickly saw that it did not resolve the issue.
I downloaded the DM Log collector Tool from this site however after watching it seemingly collect a bunch of information the resulting zip file that appears on my desktop is empty. Thus I have used the SF Diagnostics Tool. OS is Windows 8.1 Pro. I appreciate any assistance since I have lost confidence with Lenovo support!
