After a recent format (the first) of my alienware m17x, i installed vista and all of the drivers on the support cd. Everything is working fine, except it will not recognize the discrete graphics cards, and only displays the standard vga graphics adaptors in device manager.
On an alienware support thread it claimed fn-f7 would (the ac power is always plugged in btw) switch between the integrated and discrete graphics cards. Yet fn-f7 does nothing at all. After checking bios (as per some fourms) i have no access to advanced graphics settings, and the options are super limited in general. Any help would be much appreciated. Also, apologies, my knowledge of computers isn't extensive.
