Confusion with my Graphics Driver

If what DUDE said covers it, great.

Otherwise....

Yeah call the brand tech support, it's possible it's an old school jumper even, but that'll be ugly, if the case, since it's a laptop, highly unlikely and really ridiculous on MSI, if this is it.

645M for video will be fine for general use... It should be significantly better than the on-board and hopefully has it's own V-RAM.

Since you couldn't locate the system on their website, what is CPU-Z on the mainboard tab listing as the motherboard model?

That's the bios upgrade to potentially track down, and would be funny if it's not a MSI motherboard in a MSI laptop.

Check out this video and see if you can use the settings in nvidia control panel as shown in the video. That is if you have optimus.

Is this your laptop?

±ÕÇüÀâÈù ¼º´ÉÀÇ °í±ÞÇü ³ëÆ®ºÏ, MSI A617A-i5 Faust MX - ³ëÆ®Æ÷·³

It uses switchable grapics

(automatic graphics switching capabilities, but is also possible to manually set the picture as 3D settings in the NVIDIA Control Panel, select a program and specify the graphics processor will work only with the specified graphics)

From the link earlier. You can use the control panel to choose the Nvidia card within the Nvidia control panel.

Oh okay that's nice to know. :) Also, someone told me that this one is the same with my laptop:
MSI Global ? Notebook & Tablet - CX70

He said that the equivalent international model is the CX70 so that's the link. But my problem is, my laptop didn't come with an OS but the drivers for the webcam there says that it comes with the OS. Also, when I try to install the drivers for USB 3.0, I get a BSOD.

Do any of the other drivers provide at that link work for you? t seems very hard to find drivers for you.

I'm going to ask for help with the usb 3.0 BSOD.

Have a look at the link below

Not saying it will work ...
