You keep saying you have a "strong" computer, but you're running an unqualified OS. You'll need to put it on a qualified OS and make sure there are *zero* background tasks running - you should be able to get this to be a stable system - certainly many of us run rigs that are totally solid and depend on them for stable large-ensemble tracking in critical applications - but as BScout says, if this is mission critical and there are financial/legal implications if something goes wrong, you *better* have a backup. Same has been true of every recording medium for the last 40 years, be it pro tools, analog multi, digital reel-to-reel, etc.
