Yeah, gaming in a VM is fairly easy and reliable nowadays (the keyword to google for is VFIO). The cost savings is pretty substantial from consolidating multiple machines into one bigger machine. Unfortunately, there's an increasing number of games with anticheat that looks for being inside a VM.

I had similar problems with an Aquantia 10GbE NIC (which AQtion appears to be the rebranded name for, post-acquisition by Marvell), and it turned out to be the network chip overheating because it was poorly thermally bonded to a VRM heatsink that defaulted to turning on at something like 90C. Adding a thicker thermal pad and setting the VRM fan to always be on at 30% solved my problems.

Interesting! I sure hope that's not my problem because I uhhh really don't want to open up 20 machines to try to fix that.

I think it probably isn't the same problem, though, because I only have stability issues at initial startup. If it boots and doesn't BSOD in the first five minutes then it's fine... even through heavy network and disk use (like installing updates).
