about a year ago i installed win me and since then when i go to start and pull up the shut down then click restart all i get is a black screen with a blinking dash in the middle of the screen. it also does this when i have to auto reboot after installing new programs. so now i have to flick the light switch to shut the whole thing off and restart again. also were did my auto shut off go. i used to be able to hit shut down and the computer would shut it self completely off but it no longer does that i have to hit the button when it says safe to shut down. what is going on?
