If your computer crashed after each burn, there must be something wrong with either the hardware or software. First, check your IDE cable connection and the setting in the back of the unit, then make sure DMA is enabled under the Device Manager. Another possibility is that for now only Nero version 220.127.116.11 works with this burner due to the HD burn feature, you can download a trial version from nero.com to find out. As far as I know, no one recommends using the included software with this burner.
If everything still fails, then you may have a defective unit. If you really need the tech support, then you should consider a more reputable brand such as Sony or TDK. Good luck.
