My laptop keeps launching start-up repair over and over. It says it is repairing files but it only takes a couple minutes and then it restarts my computer and it just keeps doing this over and over for hours. I have Windows 7. I have my laptop automatically scheduled to run a defrag on a regular basis and I have not had any blue screens, crashes or mini-dumps (though my kids sometimes use my laptop and may not tell me that, so I will double check with them today). Does anyone have any suggestions on how to get Windows to boot in Safe mode so that I can run some diagnostics and try to figure out what's wrong? I can access the system recovery menu, but I have some files on my laptop I don't want to lose, so I don't want to reset it to factory default settings unless absolutely necessary. I sure would appreciate any help in getting my laptop to start running again. It has been running a bit slow the past week, but like I said it hadn't given me any serious problems. I did try to run checkdisk from the recover menu (from the command screen prompt) but it wouldn't let me. I did run the memory diagnostic tool (one of the options you can access from the system recovery) but it said it didn't find anything.
