Overclocking a c2d is not all that dangerous if you just want an extra few hundred mhz or so. Most motherboards have built-in protection from dangerous overclocks anyhow - they'll just reset to factory settings if you fail.
What are your computer specs?
Let's assume you have a C2D processor with a mobo that supports overclocking, your ram is at least ddr2800 and so forth.
Go into your bios at startup. Look for your FSB multiplier. It should be something like 8.5 or roundabout there. Your clock speed is determined by a multiple of that number: i.e. 300mhz X 8.5fsb = 2550mhz real speed, or 2.5ghz.
To overclock just raise either the mhz or the multiplier. Start with the mhz. Push it up just slightly to begin with. You shouldn't need to mess with voltages just yet. Save and restart. When the PC boots up check your speed with CPU-Z. Monitor your temperatures carefully, if it goes above 40c on idle it's a bit too hot. You can check stability by running cpu-intensive programs.
Rinse and repeat. Push it up until your PC can't take it, either temperatures get too high or it resets constantly. Then if you want to go higher it's time to look for more advanced tools.
