Any suggestions?

When I have the YoWindow screensaver on, after awhile it will shut down my computer, almost like a hibernation, but I can't get it going again.

I have to physically shut down the computer, and restart it. It's happened more than once, so I know it's either YoWindows, or something going on with my computer to cause it, but I don't know how to fix it.
