Followed your instructions exactly and everything seemed to be working fine. I restarted my laptop and it booted up as quick as it should be and it logged in as quick as it should be (before it was a lot slower than it should have been). I thought it was fixed but the screen froze up within five seconds of logging in. I restarted the laptop and it booted up fine again, logged in a bit slower than usual and everything seemed normal again but theny resolution changed and a notification popped up saying ''Display driver failed to start'. Thank you very much for your reply however!
