Satellite M30: random characters came on the screen even when installing

Hello

I have problems with my Satellite M30. It shows random characters or signs on the image. Other than this computer works well. I thought it could be virus, because I can see the Toshiba and the fine Centrino Logo, it starts happening during Windows loading.

So I reinstalled it but random characters came on the screen even when installing. If anyone can advise what this could be?

My thoughts are either bad graphics card or a Ribbon of a cable LCD screen mobo.

For me it also looks like a GPU malfunction... what you is to connect the external monitor to the laptop. If the same strange signs, characters will be visible on the second screen while the GPU is defective...

Well, it would be the worst case, because the whole motherboard must be replaced in case of malfunction of a GPU chip...
