I have a strange problem going on.  I bought a new game the other day and when i put the cd into the computer, nothing happend.  The cd spun for a while and made some odd, loud noises, but that was it.  I later found out that no games will work anymore.  I also cannot burn cds anymore.  DVDs and cds will play just fine, but games that are not already installed and games that are intalled will not play.  If any one can help i would apperciate it.  Thanks.
