I have an acer Aspire E15 and it got stuck. The wifi symbol first disappeared then when I restarted it got stuck. I have tried booting it to no avail. When it starts with the "acer explore beyond limits" caption, it rotates for only a short time and then stops with only one dot and hangs forever. Please help!!! I bought it with Windows 8.1 installed on it and I updated to Windows 10 about a year ago. Last September, Windows 10 was updated to the 1607 version.
