Computer uses "Standard VGA Graphics Adapter" instead of my GeForce

Since yesterday, my computer has stopped using my GeForce GTX 670 and is using the Standard VGA Graphics Adapter instead (according to DxDiag).

This happened when I was trying to install a new driver for my graphics card from its official website so that I could play a game called Battlefield 4. I am currently using a Republic of Gamer G75VW gaming laptop from Asus.

I have tried re-downloading the driver numerous times again but the installation just fails every time.
I have tried restoring my system to a date prior to this event but it just keeps failing.
Updating my nVidia Graphics Adapter through Windows Update just fails every time as well.

I have no more clue on what I should be doing as everything I do seems to do nothing, I would like to be able to play games and watch movies/videos without having to lag again and any help that I get will be much appreciated.

PS: I have included an attachment that shows my system specs

Hi, Welcome to Seven forums.

Download the required driver software that matches your hardware definition. Save a copy of the drivers in a safe place, in case you accidentally happen to delete them from your PC.

0. Disconnect from internet and Disable your anti-virus program and before going to step number 1 (Important)

1. Boot computer in SAFE mode (press F8 during restart)

2. Extract the Driver software .ZIP completely to extract all folders. Extract the .EXE also.

3. Go to Device Manager

4. Select Display adapter (in this case it reads 'Standard VGA Graphics Adapter' that need to change to 'Geforce')

5. Right click and select Properties, select update driver

6. In the update dialog select 'Browse my computer fro driver software'

7. In the Next dialog window, select 'Let me pick from a list of device drivers on my computer'.

8. In the Select driver dialog, pick on 'Have Disk'

9. Browse to the folder you extracted the ZIP file earlier (locate the '.inf' file) The .INF file would be located in the Packages>Drivers>Display>XXX_INF.

10. Run the installation, and you are done!!!

11. Restart the computer in normal mode.

12. Enable Anti-virus programs.

Keep us posted.

I have followed your instructions but it doesn't seem to be working. I still get the same result as before. Here is a screenshot that I took:

Any other suggestions?
