sorry, but you need a new screen. They are not designed to be unscratched. :(
once an e email is sent using the send button, it is gone. It is still inn your sent folder but it is now alos in the hotmail server and on its way to the destination. You can only try calling hotmail and asking if they can pull it back.
your computer has bad harware in it - probably the processor. Sorry for the bad news but if its not a virus, its your hardware.
