Cmos Checksum Bad Msi
has a Toshiba laptop with Windows XP. Several times a week, for seemingly no reason, the computer will freeze. Even after waiting a bad bios checksum starting bios recovery long time, it will not start working, so I have done 2 things--either turned it off with the on'off button or unplugging it for a few minutes.
