Try selecting the F2 option. Once in the setup, select System Logs > BIOS Events, then select Clear Log. Power the system off and remove the power cable from the back of the system, then hold the power in button for 30 seconds. Turn the system back on and hopefully the errors will have cleared.
Let us know how you get on.
