Laptop using other graphics card and not the Nvidia one.

First you need to get it to detect and use the right card.

A. Uninstall, and then reinstall, the latest graphics card driver.
B. Make sure that your Nvidia graphics card is set as the default graphics card.

Here's the steps on how to set it to default.

1. Open the "Nvidia Control Panel".
2. Select "Manage 3D Settings" under 3D Settings.
3. Click on the "Program Settings" tab and select the program you want to choose a graphics card for from the drop down list.
4. Now select "preferred graphics processor" in the drop down list. (You can see what the automatic option is listed as global setting) If you want to use the dedicated graphics card, select High-performance Nvidia processor.

Once it is running on the right one, test the system again and see if the problem persists.

My laptop no longer recognizes Nvidia Video card too. Since Nvidia card is not recognized Nvidia software is not usable. Not in Device manager or system device log. So I'm thinking its Card itself or MB. I can try this card in another laptop and this one in that to determine. Will try bios first but has anyone experienced Not being able to access Nvidia control panel and solved? Thanks very much.
