Asus K53U reformat problem... why?

Hi guys, im new at this forum! first of all please forgive me if this is in wrong section.

I have an Asus K53U i want to reformat. The thing is i bought this computer last month and had problem with the sound so i returned it and they gave me a same computer i could borrowed until they fixed my computer. Yesterday i reformated the borrowed computer, i pressed F9 when i started the computer and reformated the computer without CD... First something called "ImageX tools" showed up (i guess that is the reformat thing) so i let it proceed, and when it was done all the drivers dissapeared, except for the sound. Internet, Graphic card, Power4gear hybrid (battery thing), ELAN Pointing Device, etc... all gone. I tought when i format my computer, it will be the same as i used it for the first time...

Oh and the mouse cursor moves around sometimes by itself after i reformated the computer...

Is there another way to format it without the CD?, that is used to be when i first time used it, all the drivers etc. Because i want to keep all the drivers.

Thanks

You ran full Factory Recovery on a loaner while your laptop was being repaired? Why?

Check optional Windows Updates for newer drivers which it will supply once you Check for Updates. If you need a wireless driver to get online or there are any drivers missing after Updating, import from the Support Downloads webpage for the exact model.

They told me to do it... dont know why

In that case they should walk you through correctly running Recovery.

What drivers are cued in optional Updates? After installing them what drivers are still missing in Device manager? Get them from the Computer Model's support Downloads webpage.

everything is missing... i dont have a single driver left

How do you know this? You couldn't run Win7 or check in Device Manager if there are no drivers installed.

Exactly what drivers are you referring to?
