so i just bought a new laptop. its an HP pavilion entertainment PC with windows vista already on it. don't really like the vista so far but whatever.

well anyways, a couple days ago i noticed that every time i shut my laptop (not off, just put the screen down), windows restarts. then when i open it up, i have to sign in all over again and it tells me that windows is recovering from an unexpected shutdown. well i check for solutions but it can't find any.

my boyfriend bought the same exact laptop and his hasn't done this. i havent uninstalled anything except for windows office, sling player and vongo... all crap that im never going to use. anything that I don't know what it's for I leave on here. has anyone else had this happen with their vista? is this a common problem?
