When I turn my laptop on it only shows white.
Okay so when I turn my laptop on I can hear everything starting to work then they are fully working but my screen will only show white. I found out it's the password page but I see white no matter what. I hooked up a external monitor, entered my password and I was in my laptop, I could only see it on my monitor. I can't do anything because all my applications open on my lap top cuz my thing is set to expand. I don't know what to do. It's been like this for a bit, I'm not a computer part genius so I don't know what lots of the parts are.
