My Acer Laptop was stuck on the logo after the windows auto update. My laptop was running slow so I decided to reformat it and was changed from windows 7 to windows 10. As I am using during my work time, it suddenly shut down and there's an automatic update. And there it was already stuck on the logo. Could anyone pls help me how to fix this. The technician who did reformat have no idea on how to fix my laptop
