Windows 10 update

Today I tried to upgrade one of my machines. It was running on Windows 8.1 and should be able to run 10 (as the specs state at least). After hours the machine restarted and finally I saw the new desktop environment. But working was rather painfully. Every 30 minutes (exactly) the machine stopped to work with an error message (INTERNAL_POWER_ERROR). That is not what I wanted and I decided to go back to 8.1
