Are you saying that you can still use the computer even after getting the 0xc00000e9 message?
From reading you post carefully, it looks like the error is from the DVD drive in your system.
A new external DVD drive is under $50 and much less that taking the laptop to a repair shop. And the eternal DVD drive might have usefulness beyond you present problem,. So I would suggest getting a external DVD drive. If Chou buy it locally, not on-line, you may be able to return it if it does not solve the problem.
