I shut off my computer earlier today and when I tried to turn it back on, it will not load beyond the blue login screen. I've tried starting it in safe mode but again, it won't go beyond the blue login screen. I've tried repairing it and it says that there is no problem. When I try to run the command prompt, it says hat it can not complete the task because a system repair is in process. Please help me, I have important files om there for clients.
