I was using the guide to change video cards and after you uninstall your display driver it tells you to boot into safe mode. I set it to boot into safe mode and now it wont load. It is stuck in an infinite loop and it doesn't change if I switch the way it boots. It will restart right away if I select anything besides start in normal. When I select this, it loads the windows loading screen, flashes a quick blue screen with some writing that happens so fast that I can't read it, then restarts. Any ideas on how to fix this?
