Hi Brautigan
Welcome to the ROG forum.
Rename the bios file to - M10H.CAP
You don't need to rename the bios file if using the EZ Flash 3 utility, you only need to rename it when using the bios flashback feature.
After reading your post reinstalling windows is what I would have done too. I let windows 10 install the necessary drivers then just update the graphics driver. If using an Nvidia gpu 388.13 is the latest.
Good to hear everything is working, now time to have some fun ?
If you have any questions about anything please ask or if you like, you can show us some performance results once you get her set up.
