Disable Crossfire, try another gpu, even a cheapo one so you can cross that out. Also try with only 1 ram stick in case one of them is bad too. I had an issue where it would freeze and restart when I had 2 sticks of the same memory.
It mentioned the security update was approved Jan 16 but only the Dec 5th version is available for download.
IMO I think you jumped the gun on releasing this article when the new patch is not released publicly yet.
Stop blaming the computer, it is google.
Recent google updates to chrome basically made it slow and according to google they know about this but these measures were implemented as a security feature.
