My son was playing a game this weekend that is (was) on CD-ROM.  During the game, the CD exploded into a thousand pieces.  We just bought our Dimension 4600 in April/May time frame.  Does anyone know if this is covered by warranty?  Also, I can't seem to find my "service tag" or "customer number".  We don't have the original packing materials anymore.  How can I find these numbers as all of the customer service seems to refer to them.

Thanks for any and all help.
