Lite-on SOHW 812S reboots memory rrors

Hi everyone,

I am a Newbie and need help. I just bought a DVD burner and having a lot of problems with it. Here is how my system is setup (CPU=amd athalon 1ghz, Ram=768, two hd=40GB) using Nero6 as my burning software app. I have yet to successfully burn a DVD. Here is the problem that i am expericing, when i start the burning process and it reaches half the system would just reboot. When i log into windows it stated that the system experience a serious error and had to reboot. I checked the error message closely and it seems to state something about a memory dump. Not clear if my memory stick is bad or if its something else. I contacted Lite-on support and they were not able to help. Please help if you can.
