I recently changed my graphics card. While the card was out, I decided to change out the original year 2007 battery. I had no CMOS problems before, but I thought that since the battery was over 5 years old and buried under the graphics card I should change it. Now I get a checksum error telling me that it will reset to the defaults. Is there a driver that I should have installed? The error does not occur at every restart, only when I unplug the computer. I checked the voltage of the new battery and it is good (3.2 volts). There are no problems at all with my computer, unless I unplug it.

A graphics card replaced along with the CMOS battery replaced would trigger the hardware reset only once.

When you unplug/disconnect the power cord of a system...it's the same as manually turning off the PSU.

In some cases, the CMOS battery will then automatically reset to default CMOS settings. I've experienced this.

There is no reason to unplug the system, just shut down Windows.

I would go into the BIOS...elect the "optimal boot" options...save by hitting F10.

See if the previous behavior continues.
