When I attempt to access my DVD drive for write purposes, it sometimes causes the system to reboot.
I have replaced the DVD drive (3 wkk old). This happens on several programs (Nero, NTI, 1 click DVD Copy, MS Media Player) so probably not application software. I have uninstalled and re-installed driver. Problem is intermittent as all good problems are.
Computer is a Gtaeway 554GE and DVD drive is Hitachi HL-DT-SD DVDRAM GSA-4163B.
