when ever i insert a cd window media centre stops responding, also nero does the same, Explorer still reads the disk wont load, stops resonding too

How old is your PC ? Has the problem started recently ?
Is this an upgrade installation of Win 7 over Vista ? If so, did you have the same problem before ?
A little info on your hardware also helps forum members help you with your problem.
Apart from all the bla bla above, you can check this to see if it helps.
