Nvidia GT640 2GB
As per MSI your system might be using switchable graphics to be able to use the Intel(R) video controller and the third party video card from nVidia* (it seems to be called GPU Boost technology in their site).
You can check on the Device Manager under display adapters to see if the two video adapters are listed there.
If not, possibly your system might be set for power savings which could disable the nVidia* controller or the other video controller could be disabled at BIOS level.
Try setting all power settings to full power, update the BIOS of your system and set BIOS default's and check with MSI if the issue persists. For BIOS downloads and drivers for your system you can refer to:
