(noob) how can I overclock a computer?

Solution
Overclocking the CPU and RAM is normally done in BIOS/UEFI, though there are software overclocking methods that work from within Windows.

Overclocking the GPU is done via software - I know the AMD driver includes rudimentary overclocking options, I don't remember if that's the case for Nvidia drivers too. But in any case, there are better utilities for that, like MSI Afterburner.
