Over the past few days I have been experiencing an issue where my ASUS Z97 Pro Gamer will only post every other time I boot it, requiring me to boot the my computer twice. Usually, when I turn my computer on, I walk away from it for a few minutes then come back. Since this issue started occurring, I have come back multiple times to there being just a black screen on both of my monitors with no response from any inputs. This morning, I stayed and watched my computer turn on where this time it just stayed on the ASUS splash screen until I turned it off. So far, the computer always seems to boot perfectly fine on the second attempt, and I have had this mobo for 5 years now without any similar issues. Any suggestions about what may be causing/any solutions to this issue would be appreciated.
