Hoster shuts down my computer

[is14fun]

Thanks for your replies. I have the latest updated installed. I tried a backup copy of my database and got the same results. The second I hit apply changes, it beeps and the screen goes black. It acts like it has shut down. I have to restart computer and wait for all that start up crap. I looked at the event log but nothing is recorded there, I guess it happens to fast to record. I'm at wits end with this. I have run registery cleaners, virus scans but nothing seems to help. I can delete files and as far as I can tell, use all the other functions of the program. The problem is when I try to edit a song and apply the change.
