I have owned a Lenovo Z575 that worked fine until now. But today, during the middle of my browsing., the screen turned white!
I turned off the computer out of panic. Now, when I try to turn it on, all I'm greeted with is a black screen. Can anyone please help? Thanks.

I blew at the vents just then. So, I should take apart the computer and see if it's the graphics card?
