Answer #1
The driver is not installed, Get it from here:

For future reference, You should ALWAYS install the needed drivers after you reinstall the OS.

Answer #3
You’re sure it has the graphics card and not onboard graphics then? screen shot your device manager and your dxdiag graphics screen.
uninstall all drivers, and remove device from device manager. Scan for hardware changes, and reinstall new driver from Nvidia.

Also, What OS are you using? And is it 32 or 64 bit?
Answer #6
64 bit
Answer #7
What video player are you using?
Try going into its folder and right clicking and selecting “run with graphics processor” -> “high performance nvidia..”
If that works then put a manual setting into the nvidia drivers for that player executable.
Answer #8
vlc media palyer
Answer #9
I think vlc uses gpu decoding, so try my idea of “tun with high performance..” (a few posts above).
