HP Touchsmart 520 - Driver - Fresh Install

Hey all,

I have a HP Touchsmart 520 PC.

It has always been on Windows 7 Home Premium 64 Bit.

It was running a bit sluggish so I stuck in the Windows CD and did a fresh install.

It has now completed and it's on the setup page such as "Keyboard language", "country" e.t.c.

Problem is:

I have no drivers. My mouse is no longer working, my keyboard is no longer working and my touch screen is no longer working.

This means I cannot complete the set up and I'm stuck on that page.

I've tried a wired usb laser mouse and a wired usb keyboard, but neither are "working".

Any help would be brilliant, thanks a lot.
