I had a laptop that started getting UNEXPECTED_STORE_EXCEPTION bluescreens every time I used it. After putting a bunch of time into trying to fix it (including updating all the drivers, and replacing the RAM), I gave up and bought a new laptop to replace it, since I had to assume it was some kind of hardware issue. None of the diagnostic tools you mention gave me anything either (though I don't think I tried SeaTools; the rest I definitely did). It's also a very compact laptop and I foolishly coated the fans and heatsinks with weed vapor residue, so it was quite possibly a heat issue, and one that couldn't reasonably be fixed without a soldering iron.
If this is a desktop, you could potentially trying swapping out various parts to try to isolate the specific device that's causing it. Beyond that I'm afraid I don't have any useful advice, sorry.
