So my current pc is in the shop and I'm stuck with this. I have seen people overclock the processor up to 4.0ghz. I was wondering if my cooling would be able to handle that or maybe even 3.5ghz. One more thing, I am a beginner at overclocking and have never done it before. I was poking around and I saw that the BIOS menu where I would overclock it is locked. How would I unlock it?
