On Thursday, I tried to overclock an Intel Pentium E2160
After that, when I starth the PC, it's beeping very fast for 8 times and then is restarting. This circle lasts for about 4 seconds. That Happens again and again.
My settings:
Before OC: CPU and Ram voltage - default
cpu multiplier - x9
cpu frequency - 100MHz

After OC: CPU and Ram voltage - default
cpu multiplier - x9
cpu frequency - 125MHz

The pc is not mine so i need to fix it or i will pay for it.
I am also able to change the CPU because i have one Core 2 Duo (but i don't know if this will change the settings)

Any answer that is logically explainable is aproved
