Why can't I use hard jumpers to restore CPU frequency

Q: I've been overclocking the CPU a few days ago, restart but there is a black screen problem, but because my computer's motherboard is a soft jumper motherboard, only after the power-on into the CMOS to change the CPU frequency settings, and black screen so I can not complete this operation, how can I restore the frequency of the CPU?

A: Generally you can use two methods to solve your CPU overclocking after the computer can not start the problem.
1. Press the Power key on the chassis to turn on the computer while holding down the insert key on the right-hand side of the keyboard, which most motherboards set to allow the CPU to start at the lowest frequency and enter the CMOS settings. If it does not work, you can press the home key instead of the insert key to try. You can reset the CPU frequency after successfully entering the CMOS.
2. If the first method cannot be achieved, you can follow the instructions on the motherboard, open the chassis, to find the motherboard control CMOS chip power supply of the 3-pin jumper, the jumper into the clear State, the elimination of CMOS parameters can also achieve the CPU at the lowest frequency to start the purpose. After starting the computer can enter the CMOS, reset the CPU, hard drive, floppy disk drive parameters can be.
