could someone please tell me what overclocking is and how it is good and/or bad and also how to do it if i wanted to. Thanks!
Edit: i have a intel pentium 4 3.0 Ghz

Overclocking is running computer components faster than their stock speeds. If you would raise your processor's speed up to 3.4 GHz, for instance, that would be considered "overclocking." What motherboard do you have, and what cooling do you have on your processor (i.e. stock cooling, custom cooling solution, whatever)?

Intel D102GGC2 is the motherboard and well it is a stock emachines T5082 with a gig of extra ram, thats about it. and how would i go about "overclocking"? thanks! oh and i also have windows vista, if that helps.

I hate to break the news to you...but most companies lock their BIOS so you can't overclock and then try to return it unch....

i don't want to return it i'm simply curious. i like knowing stuff. thats why i come here

If you're still curious, there's an overclocking FAQ in the Cooling and Modding section, courtesy of CMH.
Here it is: http://www.techspot.com/vb/topic70998.html

that's only on certain chips and production runs.

thank you grafficks, that is exactly what was looking for.
