Computer re-starts while burning dvd-r/+'rs?

hi i got a 1008IM dvd-writer…in the beginning i could burn a DVD-r/+r with no problems at all…after 3-4 burns my dvd-writer just stopped working, it couldn’t burn dvd-medias anymore…now the computer restarts by itself. Anyone have any suggestions ? plz i’m really confused…and i got the latest firmware too, 0658 …

Please post your full system specs.
Your problem could be due to a number of different things.
If your system is overheating, this will cause it to restart.
If you have a bad/inaccessible memory address and not enough RAM, this could cause your PC to reboot inexplicably.

Okay pc is this:

40 GB HD SAMSUNG (PARTITIONED)
256 MB SDRAM
GEFORCE 2 MX/MX 400
DVD-WRITER BTC 1008MI
P4 1,5 GHZ
MICROSTAR-6391 (MOTHERBOARD)

Maybe it is a powersuply prob.
