? laser head failure

For some reason, my 411s just won’t write DVD using Nero I’ve recently had my computer shipped 3000km across country, everything else seem to be working fine… I’ve tried burning CDs, that works, reading DVD, that works, and also tried to create data DVD using Nero CDSPEED, that burned DVD fine.

It seem to stuff up after caching of files has finished, and my computer just crashes! I haven’t tried burning with other software, which one should I try?

Would appreciate it if someone can give me a suggestion to get my DVD burning ability back.

Thanks in advance
