My 360 has been slowly but surely giving me signals its ready to die.  COD 3 has been locking up whenever I get into a good session (and I'm actually winning.)  Now I can't get a anything with a disc in the drive to start up.  Of course I'm looking forward to Microsoft support to come to the rescue since it's still under warranty.  :|

Anyone know what's wrong and if I should just fix it myself ???

Update...almost 8 months later...

Sent it to MS and received a refurb unit, that lasted until January 2008.  Now it has the Red Ring of Death.  I guess I'll be sending it back again.  Of course, the warranty doesn't cover lost playing time :(.
