I own a Acer Aspire 5315 series that has alot of important pictures and information on it that I need. I was defraging and cleaning out some files to make it operate more efficiently, and I must have deleted something crucial for the computer to function correctly. After rebooting it, It displays a window that says "Startup repair is checking your system for problems" and has a loading bar with a FINISH button at the bottom. After about 5 minutes another smaller window pops up and says "Startup repair cannot repair this computer automatically" then gives me the option of sending or not sending the information about the problem. Then the computer proceeds to shut off again. PLEASE HELP ME, I HAVE LIKE 5 YEARS worth of important informatio I need
