After having my older computer stored on it's side for a few months, when I turned it on, the screen is half black and half blue, no desktop, so I don't even know if it's loading Windows. Is there a fix, even temporary, so I can get some info off my desktop? I don't need to get on the internet or access any downloads, I just need to read something that's on the desktop. It's a Lenovo Win 7 or 8. Thanks
