Hello,

Getting machine check events and reboots on my server which in turn kick off a parity check. I've had the MCE showing up in the "Fix Common Problems" plugin for awhile but been ignoring them since no real issues were happening other than the warning...
About a month back I had a flooding emergency and had to pull the power on the my tower and throw it on the high ground.

CPU: Intel® Core™ i7-5820K CPU @ 3.30GHz

These are the errors, I pulled these from the diagnostic download, let me know if more files are needed.

If that's the only MCE that ever shows up, then ignore it.  Some systems, for some reason (maybe they were fab'ed on a Friday) issue an MCE when the kernel brings the cores online.  Not an issue
