Unhandled exception error or restarts with Nero



I just got a Lite ON 40125S and Nero and when I try to burn a cd I either get an unhandled exception error followed by a reset, or the computer just resets druing the burn. I have ungraded the firmware on the burner to the latest and Nero to and still have the same problems. I have freshly installed XP and have disabled IMAPI burning.

Abit KT7A raid

If anyone knows how to fix this please let me know.
