I have a Plextor PX-708A DVD Drive in a computer that uses Windows XP Home and has 1 gig of ram. It ran without a problem for more than a year until today. After writing a DVD data disk using Nero, the disk ejected and the computer re-booted. Plextor technical support had me swap cables, run a diagnostic test with the IDE cable detached (it passed the diagnostic test), use msconfig to disable all programs in the start menu, and remove and reinstall the device. Nothing worked. Here's the mysterious part: if I use a DVD (video or data) from a manufacturer, it runs without a problem. If I use a CD or DVD that I previously created (video or DVD data), the system crashes and reboots. It does not matter what brand of CD or DVD. Anything that I have created previously crashes the computer. The Plextor people are stumped. Does anyone have any ideas or suggestions?
