Okay so I had a code 45 on my graphics card saying it wasn't connected when trying to install new drivers and getting NVIDIA's installation cannot continue error. So I look up how to fix this and legit every single site says to uninstall my driver and try to reinstall it. So obviously I create a system restore point, it finishes and says it created it. Then I run DDU in safe mode and clean and restart it. Still can't install drivers, it's no longer in device manager at all and even better ALL system restore points were deleted. There were 2 of them when i created the one before and now I don't have my NVIDIA driver available, I can't install any drivers because it still won't detect my card, and my system restore points are gone. So am I just shit out of luck in getting my card detected again or something? Will resetting PC but keeping personal files bring the card back? Or am I going to have to go to factory settings?

More information: GeForce GT 750m for laptops, installed windows 10 and as far as I know before the upgrade my card was being detected fine, afterwards it's got Code 45 can't access GeForce Experience and can't be detected.

I tried a reset keeping personal files but it still does not detect my NVIDIA graphics card. I really do not want to have to do a factory reset and lose ~800gb of data.
 
You don't need to lose any data, you should have a backup drive for your files. If you don't, before you do anything else, get a backup drive, copy your files to it.

Since you have a laptop, the only official drivers are from the laptop vendor, whenever people start installing drivers directly from nVidia or AMD or Microsoft, sooner or later something breaks, usually dual graphics support. Your card may have just died on you, but first thing I would do is set the thing to factory new settings, and do not touch the drivers past the latest ones available from the laptop vendor for a while, if the card works again for you.
