It sounds like you have a Memory issue, try going into the bios and raising the command rate from 1n/1t to 2n/2t or just disabling XMP/DOCP.
Software issues don't tend to go from working one moment to not working another, they are consistently reproducible across multiple systems when the same set of drivers and hardware are in use, the only component which could result in such variable behavior is Memory corrupting.
i've gamed (and programmed on) Commodore 128, early x86 up thru to these multicore high density monsters, and learned first hand just how weird software can get when hardware issues are present.
