Aspire V3-575-50TD - "No bootable device" occurs randomly

Recently my laptop would not go through with a Windows 10 cumulative update. After calling customer support, Microsoft customer service took remote access to "fix" the issue, but made it worse leading to the lack of access to the desktop. I then took the device to a Microsoft storebin which they helped me wipe the HDD and boot a fresh Windows 10. It worked well and all afterwards, but now I have a randomly occuring "No Bootable Device" screen popping up while I'm using it and when I'm not. Is this a hardware, software, or firmware issue? If either of the latter, how may I resolve this dilema?

No boot device is generally an indication of a bad hard drive. If it is randomly happening, it sounds like the hard drive is going out. I would suggest you back up what you can soon and replace the hard drive. Reinstall the OEM operating system from your back up or you can purchase the recovery media from the Acer online store at http://store.acer.com/.
