The screen suddenly froze, turned off the laptop by holding the power button. After restarting got the message "Chrome OS is missing or damaged. Please insert a recovery USB stick or SD card." Tried with two different USB sticks, didn't work. Get an error "An unexpected error has occurred". 
How can I diagnose the cause of the error? 
Looked threw similar question on the forum, looks like it's a hardware/ memory issue. 
Model: Chromebook 15, c910.

    Have you created the recovery usb? If not, you might try downloading the image directly and creating the recovery stick using another computer, then trying to recover.

    Yes, I did. That's what I meant by "Tried with two different USB sticks, didn't work."

    Which Chromebook do you have? Are you still in warranty? It sounds like the main drive may be having issues, and depending on model that might be a 'send it in to Acer' situation. Lots of the models have eMMC drive soldered to the MB, so they are not really replaceable.

    @daha you have a different model that the original poster here in this thread. Please start a new thread (Use the Ask a Question button). Include your full model number (CB3-431-xxxx, it's likely shown on the same sticker as your SNID), what you are seeing and what you have tried so far and we will help you dig into it. Why were you trying it in the first place?
