Hi there, thanks for your question.
It looks like Nvidia has discontinued support for the GT 730 graphics card. Please see below for information:

It looks like GeForce driver 391.35 is the last supported version for the GT 730, so you may need to download and install that. Here's the link:

Please let me know if you need further support!
