Well, there's always risk in anything I guess, that's life for you
More often than not I think it's something like a bad combination of hardware, drivers, and luck. But again, I've had no issues with any of it nor had to do anything special to get it all running. Couple of hundred of flying hours later, still no major problems - an occasional crash does happen but very, very rarely (maybe once in 15-20 hours). Also occasionally but rarely FSUIPC has a fit (and freezes up one of the related apps), but I can normally restart/get it back without having to reset the game at all.
