Thinkpad Edge E531 white noise on screen

Here we've got a Thinkpad Edge E531. Sometimes something happens (idk what) and the screeen shows white noise (as shown in the picture) instead of what it has to show. If I suspend the laptop and then resume back, most of the time it'll be ok (some cases were reported that it didn't work too, I think so, my sister said) and it happens regardless of the OS type. Tried Arch Linux, Ubuntu and Windows 7. happens on all of them. of course I found another solution to solve the problem on linux, but I'm not sure, maybe by changing the tty by pressing Ctrl+Alt+F2.

 

 

It doesn't happen frequently, but occasionally. I mean it may not happen during 2 weeks but suddenly 6 times in 24h.

Any idea what the problem is?

I'm wondered no body has not ever seen such a problem?

Do you have nvidia gpu (710m)? Have you tried to disable switchable graphic card?

mine doesn't have fingerprint reader.
disabling or enabling discreet graphic card does not change anything.
