I have no clue what happened. My laptop was perfectly fine just 2 days ago. I woke up yesterday and turned it on only for it to give me a blue screen. Then it gave me an option whether I wanted to "Launch Window Repair" or start normally. I chose to start normally and it had the blue screen again, so this time I chose Launch Window Repair....and it took about 15 minutes to go through a bunch of processes and it finally started up. But the information on my desktop and my background was all from about a month ago. Mozilla Firefox won't start and old programs that I uninstalled are now here again. I uninstalled everything and shut down my computer only to find that the next time I started it, the same Launch Windows Repair popped up again. How can I fix this so I don't keep going back in time with all this info and have to wait 15 minutes to start it up. Thanks. P.S. A little background info...Dell Studio running Windows Vista 64 bit processor. Still have 130GB out of 320 so I dont think the problem is the memory.
