Up and Running
I received my replacement motherboard on Friday and installed it over the weekend. The replacement came with the latest BIOS, so I don't have to worry about updating it. So far, everything is running quite nicely. I have EIST enabled in the BIOS, so the system and CPU fans can spin down even more. This makes for a much quieter system. The board comes with a ~2% overclock out of the box, but I knocked it back down to stock speeds, as I don't care about overclocking.
Everything seems to be working well. Hopefully, the curse has now been broken. *knock on wood*
