How do you restore Libraries in Windows 7?

A week or two ago, I noticed my libraries were gone. When I clicked on Libraries, the window was blank, where there used to be my documents, music, pictures, and videos. If I click on the drop down arrow, nothing appears but the arrow disappears.The only documents I can find are one document I have made since this problem started, but only if i search it by its name in the explorer or hit open from microsoft word, and the last bunch of documents from word using the side arrow for recent documents when i hit Start. This problem seemed to start after I had to do a system restore because after my mother used my laptop for something, i seemed to have some sort of trojan or malware fooling around with my system. after the system restore, my computer seemed fine, although eventually i noticed the libraries issue. also, whenever i turn on my laptop since the restore, it say that catalyst control center has stopped working. i dont recall using that and dont know what it is. i right clicked and clicked restore default libraries, but nothing happened. I had some videos on there that I need to send to the person in them, and also I will be heading back to school in two months. I am a journalism student, so documents are fairly important and I need to be able to save and reopen things frequently. Any help would be greatly appreciated.
