Question PC start up message CPU fan error press F1 setup - AND - date/time resets each time. New

Jul 13, 2020
Seems a complex problem so didnt know where to put this.
Had my PC 4 years no problem but now every time I turn on my PC I get th CPU fan error press F1 to Setup message and my date/time settings are lost (generally resetting to 2009 but can vary.)
I cleaned the fans then swapped in a brand new CMOS battery. Still getting same. I've repeatedly told BIOS to ignore fan settings but looks like all settings are getting discarded after closing down - hence the new CMOS.
Help please. Many thanks.
