Now I'm pretty nervous. I did what you said above and I was able to get on my computer in normal mode now it won't restart at all. I get stopped at the screen to start in Safe Mode, Normal, Previous mode, etc. nothing works. I finally got to a blue scr9DFeen that says a problem has been detected and windows has been shut down to prevent further damage to your computer. It says to check for viruses. Technical information:
