CMOS Information Invalid

If you have arrived here through a search engine, and there’s no menu to the left click here!

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. On occasion this error will occur when you boot some new motherboards for the first time, since they have never been set up before, but on an existing system that has been up and running for awhile, it could spell trouble.

Recommendation: For a new system, enter the BIOS setup and make sure to set the BIOS parameters carefully and then save them. Now perform a cold restart, and the problem should go away. For an existing system, 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.
