Prompt to press F1/F2 each time computer boots

Updated: 10/19/2017 by Computer Hope

New hardware has been recently installed

F1 and F2 function keyIf new hardware has been recently installed in your computer, it is likely that you are receiving the prompt "Press F1 or F2 to enter setup" because the BIOS needs to verify that your new hardware is properly configured. Enter the CMOS setup, save the settings and exit. If you continue to get errors, continue to the next step.

Error or confliction with settings in CMOS

If no new hardware has been added or you continue to get this prompt, verify no error or conflictions exist in CMOS. Press the indicated key to enter setup and verify that all settings are correct.

Tip: If your time and date are not set correctly, your CMOS battery is more than likely bad. Try setting the correct time and date, save the settings and then reboot. If after turning off the computer the time and date get reset again, replace the CMOS battery.

If the time and date are correct and everything else appears to be correct, try resetting the CMOS values to their default settings.
