CD/DVD DISC DRIVE PROBLEMS??

Ok, sounds like you're having a hard time understanding the process, so let me offer some easier instructions. All Dell computers ship with a utility partition on the hard drive that contains the Dell Diagnostic Utility. To get to the diagnostic partition, restart the computer. As the computer boots, press after the LEDs on the keyboard light up green. When the Boot menu appears, highlight the Boot to Utility Partition option, and then press   to start the 32-bit Dell Diagnostics. The system will prompt you with four choices, so pick Custom Test. Locate your CD/DVD drive in the list and run the built-in self test, as well as the Read test. To run the read test, you will be prompted to insert various types of discs. At the end of the test, you'll get a report as to whether it passed or failed, and possibly an error code.

Let me know what happens! :)
