You might have some luck with SetFSB like this guy did.

You can use your BIOS to overclock it, too. Which CPU & motherboard do you have?

Marnomancer - doubtful on a branded PC. He has a Dell Optiplex

I'm not sure about a Dell, but my first PC was a Samsung OEM, and I overclocked it through the BIOS.
There are many overclocking tools out there. SetFSB is just one of them. I personally didn't have much success with such software, with the exception of MSI Afterburner.

The guy in the video mentions how he can't OC his dell optiplex (although it was a different number) through the BIOS. There is also some mention of him individually checking PLLs until he found one that worked - but I have no idea about any of that. So, I don't think it is going to be a quick or easy process.
