Reboot the computer.
If error still occurs after rebooting the computer enter CMOS setup and check all values, this includes verifying the time and date are correct.
During the boot process you will see on the screen a certain key to press to enter setup
Press and hold that key during the boot up process to enter BIOS you can load failsafe defaults or load optimized defaults ,press escape then press f10 to save to cmos to restart
You will also need to set the time and date
In the main or system setup screen you should be able to see the date and time Using your arrow keys navigate to the date and change the date. Once highlighted on the month, day, or year, press your arrow keys or your page up / page down keys to change the date.
Once everything has been verified and changed make sure you save and exit CMOS setup.
If everything appears to be correct and the issue persists try resetting the CMOS values to the defaults or Reset Configuration Data.
If this issue continues to occur after you turn off your computer off it is possible that the CMOS battery may be failing or already bad. Before considering replacing the CMOS battery try leaving your computer on for several days.
If a BIOS update has been run on the computer the values stored in CMOS may have been reset. Enter CMOS setup re-enter all values and then save and exit CMOS setup.
If you're unable to enter the CMOS setup or after running a BIOS update your computer no longer keeps its values the incorrect BIOS update may have been installed for your computer or the version downloaded may be corrupt. We suggest trying to update the BIOS again or reverting back to an earlier version.
Hope it helps

For your problem the computer may display a prompt to press F1/F2 or any other key to enter setup each time the computer boots as a reminder on how to enter CMOS. However, if the computer asks to press F1/F2 (or another key) to enter setup and does not continue, this may be caused by any of the below reasons.
New hardware has been recently installed
If new hardware has been recently installed into the computer, it is likely that you are receiving the prompt "Press F1 or F2 to enter setup" because CMOS needs to verify that the new detected hardware is properly being setup in CMOS. Enter CMOS setup and 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 key to enter setup and verify that all settings are correct.
If your time and date are not set correctly, your 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 battery.
If the time and date are correct and everything else appears to be correct try resetting the CMOS values to the defaults.
If you continue to receive the prompt to enter setup each time the computer boots up and you have attempted to follow the above suggestions, your CMOS battery is bad. We recommended that the CMOS battery be replaced.
hope this will help you.
