We use an Acer Aspire laptop at my job. My boss asked me to switch it back to Windows 7 from Windows 10 because he didn't like it. After I did that, though, it stopped starting up. The Acer logo pops up but then it immediately goes to a black screen. The power lights and fans are still going so I think it's on but it's not loading Windows.
