Bought one of these 12.1" screens and have a few troubles with it.

I fitted the PCI card correctly, plugged it all in. Booted up PC and the screen is really dark (the brightness scroller has no effect although the seller who i bought from had it working) So i assume its a software problem. The screen is dark so its hard to seewhat im doing - i need to install the drivers which i have done but i dont know how to install them becuase they are 3 sub folders called Utilities, standard bios and custom bios and windows doesnt like that either.

Will the brightness be fixed with the drivers? How do i install, if you search keycorp k57 drivers another thread from this place comes up and a member called Shez has same problems as me... would really appreciate any help here guys.
Cheers
