A while back, I experienced all manner of issues. Errors I saw were:
Interestingly, Linux didn't give a flying fuck and never even hiccuped once. This is why I initially thought I had an issue with Windows 8.1. Go Linux go.
I rebooted into some specialized memory testing to prove I had memory issues.
I was working on building an entirely new system and had started with a case and power supply replacement. Apparently I had damage to my earlier power supply, because all my issues magically went away.
I have no notes for this
(run chkdsk, revert video card drivers)
