WHITE screen on my Lenovo S400 idea touch / windows 8?

I believe I have a virus on this lap top, when I turn it on, I have a complete white screen, I can't go forward with anything.
Anyone have any ideas?

If it's completely white all the time from power on then it's probably a problem with the signal to the panel. White screen can be a symptom of the data lead to the panel being faulty, or having a little bit of corrosion on the contacts.

It's fixable but would require quite significant stripping down of the screen.
