Given the way the game stream loads, this sounds like an issue with the SSD or the controller to which it is connected. Plopping in another SSD or an old HDD and installing the game there will help eliminate the former, you'll need to either try different ports with your SSD, use another motherboard or install another controller to attach the SSD to in order to eliminate the latter. I may have overlooked it, but I didn't see anything about updating your chipset drivers. The only other thing that comes to mind is a possible PSU power issue, but usually it doesn't manifest in the way you have described. You really need to get some other MMOs going on it to see if the problem can be reproduced or if it's specific to BDO, or grab a bunch of similar components and swap them out one by one. You've mentioned changing RAM settings, do you have a different brand you can try? I'm going to assume you are using a set that is on the tested as working with your motherboard list. I really would test a bunch of other games before you start going down this sort of route though, there simply sometimes are certain combinations that BDO just doesn't play well with. I admire your resolve, if I was having those kind of issues, and if no other game was affected, I doubt I would still be fighting with it a year later if I had failed to improve the issues in anyway.
