Thanks Denise. If the F9 recovery isn't working it means the recovery partition was deleted or damaged.
I'm not sure why the people you have been working with didn't recommend getting recovery disks from Asus but that's my recommendation. From this link: http://us.estore.asus.com/
enter k52f in the search box in the upper right corner and click the search (magnifying glass) icon.
A new page will open. Click Notebook Recovery Software
and you can order the recovery software. This will put the laptop in it's like-new state.
These disks contain not only the Windows operating system but the hardware drivers and software that originally
came with the laptop. This is something you won't get from simply re-installing Windows.
If the issues with your notebook screen and monitor are related to someone else working on the laptop as you indicated
above I'm a little hesitant to work on that. If, after restoring the laptop with the rescue disks, the issue still persists (which I don't believe it will) I'll be happy to work on it.
