I hope to get some guidance soon

Did you try running the command suggested in the error message?

Greetings and welcome,

Well, the Automatic Bug Reporting Tool (a.k.a. "ABRT") is definitely complaining of a MCE (Machine Check Exception) which, as it even reports, is usually a hardware error.

Have you looked at what is under the directory that ABRT created (e.g. "/var/spool/abrt/oops-2017-08-12-03:03:54-16376-0")? Something tells me that more info of what caused the issue should be under there. Mind you, it might not all be human-readable, but there should be something to let you know what caused the crash.

If you want, take a listing of that directory and post it here, and we can see what you have there.

HTH. Let us know.

You might also check /var/log/mcelog.
