   • Windows 8 / 8.1
     - disable driver signature enforcement (IMPORTANT or the drivers wont be installed)

     Restart your laptop and enjoy.
   

If you need help with anything...just say. And if any file is removed, just report and I'll upload it again.

 

Glad to hear you got it all working Enjoy your games now

 

Thanks...
I just got one problem: power problem!
It's too much for the charger to have a i7-840m + a 485m + 2* 2gb ram. I can only have 2gb of ram with this configuration.
So I replace the i7 with a i5 to have 4gb of ram.
I think we can't have all we want...

 

It's the standard brick plug, you have the 300W brick right? A delta 330W brick from the latest units could give you the extra juice you need.

 

My laptops charger don't say how many W it has, but I think thats the probem...I think I'm gonna save money to buy another with 330W.thanks for the tip.

 

If that still does not work you can grab the power box which allows 2 to plugged in.
