Hi, every tim i try and convert an AVi file to DVD format my Laptop turns its self off, why does it do this?

Do this:
Right click on my computer, properties, advanced tab, and in startup and recovery settings uncheck automatically restart.

Now, next time the computer won't restart but present you a blue screen with error description.
Write down this error.

I suppose it's some kind of conflict.

Thanks for your reply, just done it now, il keep you updated
Cheers
