I did not make any changes to my computer since I bought it at the store. In the beginning, the computer did not make any noises, but started about two months ago.
I did open the computer before and I think it was coming from the hard drive. The thing that is puzzling to me is that the computer starts to freeze up after I start running a few programs like Mircosoft Excel and ITunes. I don't know that much about computers, but I always though that RAM and not the Hard Drive is involved after programs are open.
