The suggestion on these forums of reseating the gpu worked for me, I kid you not. I was getting iomap64.sys windows 10 boot crashes. Removing AIsuite fixed the issue, but I wanted to use it, if anything just to monitor cpu temps. SO i cut power to the board and gpu, and removed it. sat it on some cardboard for a couple minutes. Also removed cmos battery just in case since I didn't have many custom settings. And no more boot crashes.
