I currently use DDU (Display Driver Uninstaller) to remove my GPU driver before I update them. Basically, it goes like this:
Download the new driver installer from NVIDIA. Boot into safe mode. Remove current driver with DDU, restart PC. Install new driver, restart PC again to get new drivers without any problems.
I do it like this because sometimes my NVIDIA control panel disappears if I don't remove the previous drivers first. I've been looking into getting a new CPU that doesn't have integrated graphics (Not that I don't want an iGPU, just the one I'm looking at wouldn't have one). Will my PC not work correctly because there would be no iGPU to render the display inbetween the removal and updating of the drivers, or would it still render fine?
If you need to know, I have a GTX 1060 3GB, but I don't think it really matters for a question like this
