System shuts down

PC shuts down PC shuts down battery has reached critical level

Not sure what this means, but my PC its shutting down at random for no reason.
When I power it up I get this message. pc shuts down battery has reached critical level
make sure that the battery is recharged before Windows is restore.

Then Windows restores and at random again it shuts down.

This is a Tower NOT a Notebook, it is plugged into a UPS.

    Try a new CMOS battery. CR2032 batteries are typically the right size. Or, try updating your BIOS.

    I updated the Bios recently, I thought about the CMOS battery but I can't find it.
    (might need to remove some part to confirm)

    yes is connected thru USB as well.
    Its icon on the task bar says that it is fully charged.
  4. the last option is to disconnect USB cable between them...

    ups send shutdown signal via usb

    Then, the USB UPS is your problem. It thinks your pc is a laptop. Unplug it and try it.



    didn't thought of that....

    I will try this later tonight.

    thanks.
