I ran a system recovery when it prompted me to. I have to start my computer 6-8 times before the administrator password screen pops up. I have windows vista. My system is an acer aspire 7520. The screen starts gray and fades to black but nothing else so I just do a hard shut down and have to keep doing it until the windows password screen comes up. When I ran the test/scan it said that a patch is preventing the system from starting. . . . that is all I have and I don't know what to do from this point? Please any help would be greatly appreciated!!!!!
