      I have a Acer desktop that came with Vista, now running Win 10.

      On bootup today it only gets as far as the boot screen, and gives the message:

      CMOS checksum error – Defaults loaded
      Warning:System is now in Safe Mode
      Please reset CPU frequency in CMOS setup.

      I went into every page in the BIOS but could not find anything that refers to CPU frequency.

      So I had it load the system default settings, and it is working again.

      Any thoughts on what might have happened here? I am wondering if it is reaching end of life.

      That’s an older system. If you haven’t changed the CMOS battery on the motherboard, you might start there. One of those coin-sized batteries, possibly a 2032.

      Also, on older systems/Notebooks one might see an encapsulated battery that may be made up of 2 or 3 smaller batteries, those may be harder to find.

      Before you wonder "Am I doing things right," ask "Am I doing the right things?"

      I have a Acer desktop

      If you post the exact model no. of the Acer it be possible to find a schematic of the mainboard showing where the CMOS battery is located or use somethin like Speccy to identify the mainboard (Direct download link for Speccy Portable: Speccy).

      Hope this helps…

      Good idea to change battery. I should be able to find it.

      I replaced the 2032 battery a few days ago. No error messages since then.

      Thanks for the help.
