Thanks Geoff, I wish I could just run my computer over to you to check out but I'm guessing it'll be cheaper to take it to BestBuy or somewhere to check it out?

I agree with you though. I won't use it for now cause I don't wanna totally mess it up, but damn, how the hell can I lose a disc inside the computer. It MUST be tightly sitting somewhere.
Thanks for your help.
