How do I completely reinstall Nvidia GeForce drivers?

I ve been using GeForce experience to keep my GPU drivers up to date. But my computer has been getting extremely slow as of late, with average framerates in GTA V dropping from 120 FPS (maxed out settings) to 15 FPS. I ve been troubleshooting, and now it s time to troubleshoot the GPU drivers. A simple rollback won t do, the problem started months ago and I don t remember exactly when, and I don t want old drivers causing problems with the games that DO run smoothly.

So my question is, how can I WIPE all of the GPU drivers, currently installed and any remnants of older ones, and get a clean install of the latest ones?
