Yesterday, I installed iTunes and was asked to reboot. When I hit reboot, my computer shut off instead. When I turned my computer back on, I got the blue screen of death. I can't start windows normally, repair windows, use the last best known configuration, reinstall the operating system, or even enter safe mode. I have absolutely no access to my computer. I have many important files on my hard drive that are not backed up. How can I fix this blue screen and recover my files. I desperately need these files and can't afford to go to Geek Squad and pay $318. Can someone help me?
