I have a brand new Toshiba Satellite C660 laptop. But it doesn't work and in a fit of rage I opened it up because after sending it to them back 3 times they still didn't repair it so now I need to find my problem myself.
The laptop starts normally, it works ok, until I open an internet browser or some other software, then the screen starts to flicker or even turn itself down.
To give you an example: I open google, it works normally, I start typing "wedding photograph-" and the second I pres "Y" the screen goes completely black. I press backspace and delete the "y" and the screen lights up once again. It happens with a lot of words and websites, for example a page will load up, but when I scroll down, past a certain point it will start to flicker or turn off again.
I've reinstalled, deleted, updated everything.
What can it be? If I connect the laptop to my TV both of them work perfectly and the laptop screen won't flicker until restart.
