Windows 10: Random Shutdowns

So, I work in the I.T. department for a large company and we are all baffled by this new issue. We ordered a handful of OptiPlex 7050's because we need the large case for cards. I installed Windows 10 Enterprise, then I installed a secondary NIC and a NVIDIA QUADRO K620. I also upgraded the RAM to 32GB and added the PCs to our domain. I installed all needed drivers and updates. I then deployed one of the new towers to production floor. After about an hour and a half the machine crashed. I pulled it off the floor to monitor and over the course of about 24 hours it crashed every approximately every hour and a half. Regardless of being logged on with programs running or just sitting at the login screen. I also setup a second machine for comparison and it crashed as well, albeit much less frequently.


Here's where I found something interesting. I was reviewing the windows logs and I found that right before every crash we got a Warning, Source: Hyper-V-Hypervisor, Event ID: 157. "The hypervisor did not enable mitigationa for CVE-2018-3646 for virtual machines because HyperThreading is enabled and the hyoervisor core scheduler is not enabled. To enable mitigations for CVE-2018-3646 for virtual machines, enable the core scheduler by running "bcdedit/set hypervisorschedulertype core" from an elevated command prompt and reboot.


The thing is, these are not virtual machines, they are full on, physical towers. Why is this Hyper-V-Hypervisor dictating what's going on?

Random shutdowns

Right after I got everything back together and re-applying the HS and thermal paste, I've been getting random shutdowns. It's only been two so far, but I've just been sitting at the desktop. Any ideas?
