as the title says my rift goes black randomly in practice/race , single/multi player . I have sound but no picture in my rift but i have picture mirrored on the monitor,there is no particular pattern as to when it happens . I can do practice , Qualy & be half way into a race ( 10-15 laps) when it happens . Deleted player JSON file & controller JSON files but this did not help . Now i did replace my hard drive & had to download & re install everything so it may have something to do with my settings , any help/ideas would be much appreciated .
