Sorry about it but I was interested in the solution too, but haven't found it in the previous pages.
Would you be kind enough to tell it again ? Thanks !

Of course, you just need to make sure the CrossFire option is disabled before starting the miner. There is a switch under AMD Settings > Global Settings.

This fixed the problem for me. While 17.9.1 does not have crossfire switch, blockchain drivers do and are enabled by default. On my 2x vega rig, the pc instantly crashes if mining starts with CF enabled.
