Hello Cliff, and thank you for using this service.
Sorry you are having trouble. I will help you now.
What model ideacenter is this? Also, which windows version are you running on it? 7, 8, or 10?
Please hold the power button in on the computer for 15 seconds. It will turn off during this time.

Sorry, I am out of ideas. Will opt out to other experts for review. Another expert will be with you soon. Thanks.
