I hav dropped my phone twice and it has a lot of black lines trough the screen that i cant get off. please hepl mee.

Sounds like you have damaged the screen when you dropped it to a point that the screen is showing you the black lines.
I would say the only fix for this will be to have a new screen installed in the phone.

Dropped my storm in water :/

The best way to get any and all moisture out of the phone and out of under your screen, put it in a bowl of rice(uncooked) and it will soak up all the humidity. I did that with my blackberry and it worked awesome. However I can't get my buttons to work, I took it apart, but it is all dry.

Black Line in middle of screen

Are you able to test this monitor on another pc? This will allow us to eliminate or identify as problem with the graphics card. With the monitor itself, these lines could indicate screen damage - has the screen been dropped or accidentally hit with a pen etc.. ?
