I'm sorry about the issue. When did this issue first occur?
Can you please confirm your Acer One computer has windows 7 (or windows xp, vista, or 8 or 10)?
Please reply at the box below. Thank you,
Thank you. Can you please shut down the Acer One computer. (If needed, press and hold the Power on / off button on the computer for about 10 seconds to power it off.)
Then turn it back on. Then when the Acer / Aspire logo appears, press at the same time the two keys Alt and F10 on the keyboard. Then let me know if it shows something different.
