|About the only thing I can suggest is to run System Restore (which keeps your own stuff) to a date before this problem came along:|
You will need to re-install any programs or Windows Updates that have come along since that date.
If that doesn't help then most likely the CD/DVD unit itself has failed and needs replacing. To me, this seems the most likely cause of the problem but try the Restore first.
Always pop back and let us know the outcome - thanks
