I left my computer (running 7 RC) on over night because it was downloading and installing SP2 for Office 2007. In the morning the computer was off. I imagine the power went out some time during the night because when I turned on the computer, I get a screen stating that there was an improper shut down and I am asked whether I want to boot in safe mode or not. The only problem is, I get this screen EVERY time I turn on the computer. Then, once I log in, a box pops up telling me it's searching for errors and checking the web. It doesn't find anything and closes, but I continue to be prompted upon start up with the improper shut down screen. Any suggestions?
