I've been having trouble with my PC that often goes through two POST cycles before booting into Windows. Recently, it just stopped and went to a black screen after the second POST. Along with this, my PC has been freezing randomly and restarting without warning. I've noticed that the date and time don't sync up correctly, and sometimes I get error messages saying it can't start the audio service or load GPU drivers after a forced restart. Also, my RAM speed suddenly dropped from 3200 to 2400. Could the CMOS battery be the main issue here?

The fact that your PC enters POST twice usually indicates a deeper issue, possibly related to your CPU or RAM. Just swapping in a new CMOS battery might not solve the freeze problems, but it’s worth doing just for good measure.
Double-check your fans and make sure everything is running smoothly. It could also help to test your RAM by removing them one at a time to see if the system runs more stable with just one. That could pinpoint if one of them is failing.
It sounds like the CMOS battery could be a factor, especially with the time out of sync. But those freezes and restarts might be caused by something else. I would recommend updating your BIOS first and see if that stabilizes things before messing too much with your RAM settings.
Changing the CMOS battery is a good first step. They're usually cheap and easy to find, so swapping it out can help rule it out as the issue.
