Is there some setting that makes Vista just decide to turn on my computer by it self? I turn it off (completely)..... leave the house..... come back and my PC has turned itself on at some point while I was gone. Only started doing this with Vista. I dont even understand how it could do that if it's totally turned off. But I dont know is there some "turn on PC upon network signal" or some wierd thing like that? It's just bizzare.
