Note :
a. If the steps above do not help, remove the onboard battery and move the jumper
again to clear the CMOS RTC RAM data. After clearing the CMOS, reinstall the
battery.
b. You do not need to clear the RTC when the system hangs due to overclocking. For
system failure due to overclocking, use the CPU Parameter Recall (C.P .R) feature.
Shut down and reboot the system so the BIOS can automatically reset parameter
settings to default values
