I need help re-overclocking!

[Spiritus]

Hi, when i bought my PC me CPU was overclocked to 4.00GHz but yesterday i started messing about with the bios settings and i somehow disabled the oveclock and now im back at my stock clock which is 3.60GHz

My specs are:

CPU: AMD FX-4100 overclocked to 4.00GHz (But is now at 3.60GHz after i accidently disabled the OC)
GPU: Asus Amd 7750 1GB
Ram: 8GB DDR3 1333Mhz
HDD: 500GB Deskstar
(This runs windows and has all my games on it)
Motherboard MSI 760GM-P21 FX
OS:Windows 7 Ultimate 64bit

So can someone tell me how to overclock my CPU again, and if you think its possible, an even higher OC?

I looked for tutorials but no one has done one with the same motherboard as mine so all the BIOS is different

Thanks!

P.S. If you need pictures of my BIOS just ask and I will upload some and link you to them.

I would look in your BIOS first off, chances are the original OC settings are stored in there and you just need to reload them back in. I am not familiar with MSI boards, so can't really advise what it would be under, someone with MSI experience may well pop along soon.
