Reset to actory setting (wihout CDs)

So I just bought a used MacBoo pro 17" and it's great.
NOW, it still has the previous users EVERYTHING on it and I'd like to delete that stuff. Now I know you can reset to factory setting with the original CDs but he didnt give me those just a laptop and powercord. so what do i need to do exactly?

Either go back to the seller and get the CDs or buy a new copy of OS X.

You can delete the apps, etc., that are on it that you don't want (just drag them to trash, or use the app's uninstaller), but you can't just reset the comp to the original OS without the CDs.

Try creating a new account for yourself and using that.

This isn't the same as a complete reinstall though (ie. revert to factory settings). You'll never be able to do that unless you can get a CD from somewhere.

Does it come with OS 10.4 or 10.5 though? If it's on 10.4, just buy a Leopard DVD and erase and install to the latest OS.

how do I check if it has leopard?

In the top menu bar click Apple logo --> About This Mac

If it is Leopard you will see "Version 10.5.x" (where x is a number)
If it is Tiger, you will see "Version 10.4.x"

well It's tiger so now I have a reason to get leopard.
Sweet
thanks
