Hi everybody
I bought this used laptop and know its giving me headache... 
First my power button only works when it wants so I have to replace the keyboard.
NOW in games some strange thing started to happen: some green dots appear all over the screen in any game.
I think my gpu is going to die, what do you guys think? Did someone have the same problem?
