To improve system performance, you have configured a motherboard to run with a higher multiplier than what the CPU is specified to use. Since doing this, the system has become unstable and crashes frequently.

To restore system stability, which of the following should be completed?

A. Replace the CMOS battery to make sure the real-time clock has the correct time.
B. Make sure the switch on the power supply is set to the correct voltage.
C. Back off on the overclocking settings until the system runs in a stable manner
D. Make sure the BIOS firmware supports the overclocking settings you're using
