ok I have an alienware 17 with OS win 7 pro, and it seems that when I ask the laptop to restart i.e. after a program hang or update drivers the normal win 7 goes to shutdown tells me background programs (I say yes as normal) but the thing just goes to a black screen and all fans and FX stays on, I cant get out of it until I press the alienhead down for a few seconds to manually shut it off.

I read it is some BIOS stuff but I alas am a noob to try this on my own and the laptop is under warranty still. 

I have updated all the nvida drivers for the GTX 980M and of course the OS itself.

on a side note when playing/leaving WOW it freezes, people I play with also have this problem of game freeze and think it is the drivers (which we rolled back etc) but that is another question and many agree it is the Nvid driver that pooping that up.

any help would be great.

thanks
