I have an Asus Eee pc seashell series netbook running windows 7 starter. yesterday when i turned it on it booted up and brought me to the login, as normal. But after i logged in i got a black screen with a cursor in the middle. Im using all my programs using task manager(from control+alt+del), but it stays black. i dont have the installaton cd and i tried safe mode but it was still black. how do i get rid of this problem?
