Is the a Certificate of Authenticity sticker on the computer anywhere that has a Windows 7 Product Key printed on it?

If you have a Win 7 COA sticker with a readable key you can do a clean install of Win 7.
Here is an example of a COA sticker



Here are a couple of tutorials for doing a clean install:
Clean Install Windows 7 - Windows 7 Help Forums
Clean Reinstall - Factory OEM Windows 7 - Windows 7 Help Forums

Take your time and read through the tutorials so you understand what you need to do.

You can download a Win 7 ISO from here:
Microsoft Windows and Office ISO Download Tool

It sounds like you just need the proper audio drivers installed, plus whatever program you normally use to edit photos. Should be simple solutions.
