Windows 10: Unable to save the change in BIOS even after changing the battery

I am currently experiencing an issue with my PC. When I start it, a message appears indicating a hardware change. After a few seconds, it boots up normally. However, all the changes I made in the BIOS are lost. The PC works fine even after restarting, with no problems. But if I shut down the PC and turn it back on after several hours around 8 or 9 hours, the same hardware change message appears again, even though I did not make any changes.I initially thought the battery might be the problem, so I replaced it twice. After replacing the battery, the PC works fine for a few days, but then the

Bios Battery

@Mexicanpete,
Leo suggests taking pictures of the bios settings before changing the battery How can I save my BIOS settings before replacing the CMOS battery? I need to do this myself.

 

Recent (Save Files) - Change Default Settings to OneDrive

Hello -
Thanks for the return. Before I undertake changing the Registry, I have a question.
The steps in my Registry, for my version of Windows 10, were a bit different, but I think I eventually got to the right spot.
The last step is to change the number of places you want to list in Recent Places. In my case, the default Max Display listed 50 as the number. So, if I were to change that number, how do I know the Save As page will be one of those places? Or, a similar question, will this registry change delete the tab Recent from my Save As page? This is what I would like to happen.
When I received my computer in Nov. 2016, the Recent tab was not listed in the Save As page. Something caused it to be added over time. Which brings me to this second question. Would there be any benefit in deleting the changed registry listing and reverting back to the default listing? See attachment.

cannot save changes to cmos

i have a soyo p4865pe dragon 2 motherboard that suddenly out of the blue wouldn't save changes to cmos.

when you save to exit the "y" is there but if you hit enter nothing happens and the computer is frozen. if you turn off power to reboot, it doesn't reflect any changes you made.

by accident i discovered if i ctrl+alt+del it will exit and reboot but the changes are saved. this was what i was doing for a while.

i can switch the n and the y back and forth, i can exit without saving and have no probs.
only hitting enter with "y" selected to save will freeze the system.

i have no clue why this started happening but nothing was changed or upgraded on the system and i don't overclock i just run a vanilla p4 3.4ghz 800fsb 2gb ddr400 ram system.

i thought the board was going bad but after i changed it i started thinking it may not be a bad board but maybe a bad bois chip so i came here to people who know more than i do.

i replaced the bios battery and reflashed to the latest bios before giving up and swapping out the board so i'm sure it's either a board issue or defective bios chip.

i just don't know how to check this out and maybe my idea of a bad bios chip may be dumb.

it was a good board and i really would like to save it if possible.
