Eric,
It has been a long time since I had seen those "Safe to Turn Off" Screens in Win95-98 but I think (Memory failing here) they used the same screen in both OS'.
Did check in your Device Manager under System to see if you have an error on power management?
It would help if you gave us the brand and model of your motherboard.
Take Care,
