Rehackintoshed

Hi all, I decided to re-hackitosh an old machine that was running Sierra with clover. All went well with Monterrey and OC 0.91. Machine boots up and works fine. Only issues are these messages on startup and the fact that you need to have the audio source on before booting and some wake from sleep issues. As I am not very knowledgeable about technical things can someone give me any pointers on how to get rid of these messages? Thanks Machine info: Gigabyte Z97 gaming 5 / Haswell processor 4th gen / GPU GTX 760 / 32 gb ram
