Hello, Miha!
My Laptop in fact is a 0769 model. It seems that something got really messed up with drivers or whatever. When I tried to install the Nvidia driver it said that I don't have any Nvidia hardware.
Then I installed the Intel driver and it did install, but didn't solve the problem...
I will try the driver sweeper too, thanx for the suggestion!
Thank you all for all the help, I will try to solve this problem later, as I don't have my laptop here now. Thanx!
