Can I overclock this?

I want to overclock my "Intel(R) Core(TM)2 Quad CPU Q300 @2.50GHz.

I'm a tad clueless on how to overclock. Can somebody quickly answer 2 questions:

1) Is it possible for me to overclock?
2) Link me a tutorial for what I have?

Specs:
600w Power
ATI Radeon HD 5800 series
4.00 GB RAM
64-bit Windows 7.

Motherboard
Packard Bell MCP73PVT-PM (CPU 1)

VID = 1.2875 v

Thanks.

you could oc it if it weren't for that motherboard

Agreed. Mobo lacks the settings needed in the bios to overclock.

Not a problem at all, but motherboard makes it impossible.

You will need a new motherboard, case and PSU.
