Dell XPS L702X 3D - Reinstalling everything from new due to formatted HDD's.

First off, sorry if I'm posting this in the wrong section, it's my first post [:)]

I have a Dell XPS L702X 3D. Recently, due to an error with Windows 10, I have to had to format both HDD's and reinstall Windows 10 as new. I do not have a factory image nor backup. As a result, I have lost all software that was preinstalled on the laptop when it came to me. If you can, could you please inform me as to what software I should install, what drivers to install, and how to configure anything I install so that my laptop is returned to factory condition (besides the preinstalled Windows 7 of course [:)]). I do have the Drivers and Utilities disc that came with the laptop so all I need to know in that regards is what to install (and again, how to configure them correctly). I realise this is quite a tall order, but if any information can be presented as clear as possible that'd be amazingly helpful. Hopefully, I will return to a useable laptop that I can trust not to break on me again. Cheers in advance!

If you need to know anymore details about the laptop, please just ask and I'll do my best to provide.
