Something is wrong with my acer laptop


Nov 3, 2016
I have an Acer Aspire E5-571/E5-531. Recently every time I try to turn it on it says "No Bootable Device". I've just been powering it off and back on again and then it works fine. Then yesterday while I was using it an error screen popped up with the error "Critical Message Died". The system checked for errors and then restarted and it was fine. And then today the same thing happened, except when I restarted it it just kept coming back to the same error message. I was able to get to the "InsydeH20 Setup Utility" screen by pressing F8 while it was booting up, but I'm not sure where to go from here. The laptop is out of warranty but I've only had it for two years.
