board: intel dg41wv
cpu: intel core 2 duo
ram: 4gb ddr3
can nvidia gtforce gtx750 (2gb) or higher graphics card be installed in the pc?
This 2010 year MB have only PCI Express 1.1 compatibility, while modern graphics cards are PCIE 3.0 devices. Also, old Intel BIOS is not ready for, like, dual VideoBIOS (legacy+GOP) of modern cards. I found no evidences of success with newer that GTX 600 NVIDIA card on your MB.
