What should I do if the system fails to boot after overclocking?

For system failure due to overclocking, use the C.P.R. (CPU Parameter Recall) feature by shutting down and rebooting the system so the BIOS can automatically reset parameter settings to default values. Note that AC power off is required to enable the C.P.R. function, so you must turn off and on the power supply or unplug and replug the power cord before rebooting. You do not need to clear the RTC RAM when the system hangs specifically due to overclocking. (Page 1-9)
