okay, i don't know what your using but you might wanna try coolbits, all you have to do is right click and go to core frequency and click on "use these settings on startup"
there it is there, its only a couple bytes, and all you have to is click yes to overwrite your current registry and right click on the desktop go to nview or whatever it is that your monitor is, i'm can't think of it at this moment because i'm at my school computer.
and as for overclocking the cpu... i was like that too, so where do i begin.. okay first you should look around through your bios so you could find a clock setting, which should be under "FSB" or "HTT" and should be at 200 mhz. All you have to do, is change your mhz to overclock. But be warned, when you get high enough you will need to overclock your ram, or run a divider (pretty much underclock it). And once you get to another point, you'll have to up the voltage your cpu is getting to keep it stable.. i don't think you can get any more simple than what i just said.. so if you can't figure that one out, your out of luck.
