My laptop only works if it is put in certain angles. The angles change from leaning it to its side or to the front and back. The laptop also freezes when I apply pressure to the side where the cd-rom is located.I doubt that programs are causing the freeze,as I suspect something is loose inside. I wanted to seek advice before I open it up. Please help!!

Yeah, theres probably something loose or chipped inside thats causing something to be loose. If you have time you should bring it up to best buy or radioshack or a business like thoose to see if you can get it repaired or find out whats wrong.
