Windows 7: dxdiag does not show nvidia 310m gfx card

Hi, I hope you can help me. I recently tried to run some games on my laptop and keep getting black screens (e.g. running Aion I get to login screen but it's black though I can see and move cursor and hear music).



When I run dxdiag it only shows the Intel HD graphics. But in my device manager I also see a NVIDIA Geforce 310M. I'm wondering if my laptop is set up right, but am not sure what to check?

I attach my dxdiag. When trying to update drivers the system says both are up to date. I did try a new driver from nvidia but it crashed my laptop and I had to restore the old ones back. In device manager the 310M driver is dated 10/02/2010 version: 8.16.11.8910.

Any assistance you can offer would be really appreciated and I'm happy to give more info if needed.

You seem to have Optimus (switchable) graphics.

I have no personal experience with them, but I imagine that you may need to get custom drivers directly from your laptop's manufacturer.

Here:

ASUSTeK Computer Inc. -Support- Drivers and Download UL80Jt

(32 and 64 bit versions are available. I'm not sure that these are the Optimus drivers, but I expect so.)

Install new intel display drivers first (from intel site), then install nvidia driver Drivers | GeForce (here 64bit driver)
it should work it supports optimus the only problem that laptop manufacturer sometimes locks chip drivers from original chip manufacturer like nvidia. I have lenovo with geforce 310m and intel HD it works with drivers from nvidia.
asus site offers drivers that is more than 2 years old that is bad.

by the way geforce 310m is not that powerful card its weaker than new generation intel HD graphics.. and around same level as intel HD3000.
