After one year of HiveOS i want to contribute with the most important things i learned while getting issues and troubleshooting.
All crashes of hiveos has been related to drivers or overclocking.
A skilled user probably want to locate the issue and solve that. For me its easier to start over. Fresh install of hiveos with latest driver and NO overclocking. If i believe any GPU is the issue i start with 1 GPU. When stable, add 1 more GPU until everything is working or broken gpu/riser is found.
Disable GUI on boot + enable Maintenance mode
Good luck and happy mining!
