Second, turn off in BIOS the onboard graphics and put only PCI. How to do it, I have no idea, I'm your BIOS is not seen. Look for yourself.

You have in BIOS such option as graphic mode? Perhaps there is set to intergrated. Put it on the other.

Honestly, I don't particularly understand, especially in laptops. You have switchable graphics, ie switching between cards depending on the estimated load (m. b. to try to remove a tick?). Eeee. in the browser, for example, can work installation, and when you start the game switches to discrete. Why do you have that is not working? I don't know. MB do you have a graphics card broke, I don't know.
