Question about MSI MEG X570 Ace

I have the following problem: "Devices changed ( cpu or memory) or cmos have been cleared". Press F1 to enter Bios Press F2 to run default setup This message comes up just after booting the PC. If I press F2 it changes the boot priority from SSD to HDD. (Windows is on SSD). My sata ports are on 2 and 4 respectively. I hope someone can help me with this description, if not I can answer in more detail. Thank you!
