Long before looking for a solution, first establish what is and is not working. Break the problem down into parts. Every responsible computer manufacturer provides comprehensive hardware diagnostics. Tests only hardware without any Windows or drivers to complicate the issue. If the hardware diagnostic test passes, only then move on to drivers, Windows, or media incompatibility. Remember there are numerous DVD R/W standards for the same reason why the silly 'Blue-Ray verses HD-DVD' war is ongoing.

Take it one step at a time. Do the computer hardware diagnostics report a good DVD and sound card?

Taking another tack. What is reported in Windows Device Manager? Does it show any problems with any other hardware? Also critically important information obtained before trying to fix anything.
