I have been getting slowdowns and crashes since upgrading to a new Gigabyte motherboard and a Ryzen 2700x
I also got new Ram and I suspected that.
I tried windows mem diagnostic and it reboots to a blank screen so that's no good.
I ran the windows Hardware troubleshooter and It said all 8 of the ryzen cores have errors ??

I looked in the device manager and when i click on properties on all cores I get this error message
'A driver (service) for this device has been disabled. An alternative driver may be providing this functionality. (Code 32)'
Maybe this is a red herring but would like to hear from someone else who has a Ryzen if this happens on their setup.
