@Ifriz983,
Welcome to HP Forums, this is a great place to get support, find answers and tips.
Thank you for posting your query, I'll be more than glad to help you.
I understand that you get a clicking/ticking sound repeatedly from your Omen 870-100nl Desktop PC.
In order to isolate the issue please let us know from which part (fan or speaker or Hard drive) of the computer. You may open the case and check also.
You may also follow the steps in the link: http://hp.care/2oPjRqD
Also, let us know the operating system installed on the computer from the links below:

You have a good day ahead.
