So, i must start out by saying that this doesn't happen very often. But when it does happen it's f***ing annoying. So i built a computer using a used cpu, gpu and ram. the rest is brand new. Sometimes when i start the computer, it "forgets" the gpu driver and i have install that through geforce experience. but after installing it again, after rebooting windows will either freeze at login after typing in my pin. or like a minute after successfully logging in. when this happens it sometimes reboots by itself or i hold the power button to turn it off. When it reboots by itself the gpu driver is uninstalled again, and i need to install it. I was wondering where the problem could be? I have reinstalled windows 10 but that doesn't fix the problem.
