I recently had to replace my CMOS battery - it had gone bad after only 8 months. Whenever I would shut down my computer and unplug the PSU to install a new part/clean it out/re-wire manage, I would lose all BIOS settings (RAID array, overclocks, etc).
It will say right on it when you pop out the battery. I am at work at cannot remember 100% but it was either 2016
Good luck! Hope it resolves the issue. Either way, it's only like 5 bucks and will serve as a good backup later if it doesn't resolve your issue.
