I have a Macbook pro and after a lot of trials I was able to successfully install the Windows 7 64 bit professional to it. The problem is that the device needs a graphic driver updated. I use Nvidia 9600 Gt graphic card. I tried to upgrade the driver but could not find the appropriate one. I do not know what could have been the reason that driver not responding well. Please do help me out in making the issue to be sorted. Thank you.
