My acer ES 15 laptop froze, so I shut it off. When I turned it back on, it said "preparing automatic repair" then it goes black and comes back saying "diagnosing your pc" when that's done it goes to another screen saying "your pc did not start correctly." Also gives me the option restart, sometimes just that will fx the problem. Other option is advanced options. Restarting it will just go through all the same things again. I've seen posts saying automatic updates will cause this problem and you just need to take the battery out hold the start button etc.. BUT.. My laptop doesn't have an external battery that I can pop off. In advanced options - use a device, I don't have a usb drive or windows recovery cd, and no cd drive on the laptop. None of the options in advanced options will work, or I don't know how to use them. The laptop is only two years old, I've barely done anything on it. Pretty upset with it.
