So I was updating some drivers on my PC and my PC froze. I let it go overnight but it was still frozen so I was forced to restart the computer. Now everytime I try to boot up the PC I get stuck at the Windows 7 loading screen. I've tried booting in safe mode and even tried booting to a Windows 7 installation CD, but I always just end up stuck at the Starting Windows screen. I'm thinking some drivers are probably messed up, but don't really know how to fix it without getting Windows to boot past the loading screen. Any recommendations would be greatly appreciated.
