Not so solved...
Sorry, I'm reviving the dead one (talking about this thread), but I couldn't find such a problem anywhere, and this one is similar to mine.
Well: I've got exactly the same notebook:ASUS N61JV, with CPU Intel Core i3,and Graphic: NVidia GeForce GT 325M. Without an OS. I installed it later.
At the beginning it looked fine: I didn't have black screen - I could see everything on screen, move around system etc. I installed NVidia driver from CD attached to product. And in order to test it I launched TR: Legend (one of games with very good graphic). Looked beautiful and moved fluent

until I changed details to maximum. Then I was surprised, cause it looked worse, than on old GF7
900!!. I thought "somethings wrong..."

and started to dig in Nvidia driver settings (unfortunately, I don't remember what I've changed). Big mistake. Only effect I got is so, that when I start ANY game with good graphics, there's only black screen waiting for me. Bah! One game, when I try to launch it, gives me such a warning:
Your CPU type « INTEL Pentium-II » is below the minimum requirements.
Your videocard « Intel(R) HD Graphics » is not supported.
Do you want to launch the game anyway? [Y/N]
So, maybe it does mean, that I somehow turned off Nvidia permanently, so it does not start working when needed (as Stormy said many times in this thread). :sarc: I tried many thigs, including:
- Digging in Nvidia driver settings more and more in order to find, what I've changed,
- Reinstalling Nvidia driver,
- Installing Intel driver from CD, though it somehow installed itself, maybe W7 downloaded it,
- UNinstalling Intel driver - bad choice, effect - black screen all the time. Luckily after restart, W7 installed VGA, so I could install Intel driver again.
- UNinstalling and installing again Nvidia driver,
- Finally, tried to restore system to point before this digging in settings of driver. Surprisingly - even this didn't help!! :shock:
I'm desperate now. Windows works, but games - not. That's not what I have paid for!

The only step I can think of now, is reinstalling whole OS, and starting everything from the very beginning. But this is ultimately. And no more DIGGING....
Have any clue, how to solve it?
