Have you tried entering SETUP and restoring the CMOS data to the factory defaults? CMOS data can be corrupted by power glitches and possibly Windows crashes. If you cannot get the "CMOS checksum error" message to go away (and you are sure the battery is OK, or you have already replaced it), it is possible that the data in your BIOS chip on the motherboard has gone bad. In many cases, BIOS corruption can be fixed with a flashBIOS update which can be downloaded from the motherboard manufacturer's website. Another cause may be a virus, or the worst case scenario: that your motherboard is on the way out. How old is the computer?
