Thank you for the question. Can you tell me what operating system you are using on your machine and what happens when you try and shut down?
I'm sorry about the issue. I'm another computer tech. Do you still need help with this?
Does your emachine computer have windows xp, vista, or 7, or 8, or 10?
Is there any error or message when shutting down your emachine computer?
What are you trying to delete?
Can you press and hold the Power on/off button on the emachine computer for about 10 seconds? That should shut down the computer. Then turn it back on and check.
Please reply at the box below to continue troubleshooting. Thank you.
