Clearing a Corrupt CMOS
Explanation: During the startup process the BIOS has detected that one or more of the settings or parameters it has read from the CMOS memory is invalid.
Diagnosis: Normally if this occurs it generally means that the contents of the CMOS memory has become corrupted.
Recommendation: Troubleshoot this issue as though it were a corrupted CMOS problem.
- Find the manual for your motherboard.
- Locate the “Clear CMOS” jumper on the motherboard.
- Shut your computer down and unplug it from the power source.
- Move the jumper from it’s default location to its Clear CMOS location, wait 20 seconds and return it to its default location. Note, if you can’t locate a Clear CMOS jumper, just remove the battery from the motherboard and then wait the 20 seconds and reinsert the battery.
- Now plug the computer into its power source, start the computer and boot into the BIOS setup.
- Set the BIOS to its default settings, and then let the computer start normally.
- Now restart the system and boot into the BIOS setup again, but this time create any special settings you need.
- Save your settings and start the system normally.
