I changed my BIOS settings but when I rebooted, they reappeared with the old values!

Explanation: You went into the BIOS setup program to make changes to the settings, and then rebooted the PC, but the changes were reversed to the old values when you rebooted the machine.

Diagnosis: You probably forgot to save the changes to the BIOS settings, or you selected the "Exit without saving" option instead of the "Save and exit" option in the setup program (which are, unfortunately, usually located right next to each other on the BIOS setup menu).

Recommendation:

• Make the changes again, and be sure to save them using the correct option in the setup program.
• If the changes again do not stick, you might have a problem with your CMOS battery.
• Troubleshoot the motherboard.
