Any advice out there?
For some time my windows 10 with SSD hard drive zwift frame crashes / freezes accompanied by a growling sound, and I have to disconnect the power supply and reboot.
This worked until today when after 5 attempts at restarting I gave up.
Anyone else had this? …it only happens whilst on Zwift.
Any F/B gratefully received.

Overheating due to a bad fan? Certainly sounds like a system problem more than a Zwift problem. Anything in the Windows Event Viewer? You could also try to reproduce it with a benchmarking app that works the system to the max.
