Try a different lead. I remember having massive issues with black screening on a Fury X and after buying a DP 1.3 lead, it fixed the issue.Intermittent black screen/freezing issue.
Used it for over a year and never had a issue then it started happening pretty frequent.
But they cant seem to reproduce it during testing, although they have been good enough to have another look at it for me.
Can't believe I had second thoughts on getting one when the new range came out
