I have done some tests.
I have confermed that it is limewire in some way that is restarting my computer.

1. Lime wire is the only program that produces this problem.

2. Even with a reformated computer and only windows and lime wire installed, the problem is still their.

3. after all windows updates are installed, the problem is still their.

4. I have installed all divices and programs i have for my computer 1 at a time.
And between each install, I tested lime wire and the problem was their each and every time.

I have not yet found the cause of the problem though.
And it appears to be generated at random.
Seems to happon alot more when you download more then 5 files at a time.
