well sounds like this is solved but yeah there are other ways to check if the cdrom is broken or if you computer is just jacked up...try pluging the cdrom into another computer and see if it still gets the same effects if you cant do that then try the other methods above,try runnin a anti virus and spyware programs. good spyware is right on microsoft.com its the antispyware beta or w/eif none of those work if you can do this try reloading your os and hope it fixes the problem.then if that dosnt work then you either 1 need to get it fixed or 2 buy a new one.
