I've not flashed the bios. I've had my rig running since last July. I've never had as single issue with it. Until the patches rolled out last week. Coincidence? not really.
It could have been the meltdown patch causing those issues. In fact, that may explain why apps just died and refused to run. Maybe they were using certain paths to the CPU.
God knows, but I'm not really in any mood for any more of it. Last time I checked I was still vulnerable to Spectre.
