A couple of days after coming back from a trip out of state I noticed my personal tower I built a few months ago started doing something odd. Whenever I boot now my Asus ROG Maximus X Hero motherboard only boots to the setup screen rather than booting to my Samsung Evo 960 (500GB) m.2 ssd during boot, or when restarting.
However, the ssd is still seen by the ROG BIOS on the motherboard, and is also the first boot option in the boot priority list. I have also found that I can boot into the ssd from the boot override list in the BIOS. I have tried everything from reseating the ssd in the m.2 slot on the motherboard, to resetting the CMOS, updating the BIOS to the latest version, and resetting my all BIOS settings. Though it seems nothing I have done has worked so far.
Any ideas or advice will go a long way to helping me figure out what is going on.
