OK so I know that we have alot of these ones floating around the place and I've tried all of the normal stuff. e.g. re-installing Java, deleting bins file out of the .minecraft folder in roaming, re downloaded minecraft file etc. and nothing seems to work. I'm still always getting the black screen after clicking login. :( I'm running windows Vista and all my drivers to my knowledge are up to date can anyone help me?

p.s. It works on my Laptop but then shuts it off after about a minute of gameplay.
