I have finally found a way to access my BIOS settings in my computer! I am running Windows Vista 64 bit Home Premium, a C2Q Q9400 2.66 GHz @ 2.66 GHz. 6GB of DDR2 800 MHz RAM, Radeon HD 4850 512 MB GPU. I have never done this before, I am aiming at clocking my CPU from 2.66 GHz to 3.00 GHz. Should I be able to do this with my stock cooler? I heard overclocking can be extremely dangerous. Such as causing your system to constantly crash, not to boot, become unstable, cause data corruption, and even damage/break components on your PC. How do I do this properly, without those things happening?
