Hello;
Allow me to welcome you to the HP forums!
Sorry, but we are not HP Tech Support; instead, this is just a community self-help forum staffed by mostly by volunteers. We have no way of diagnosing or repairing your PC from here. All we can do is provide links to troubleshooting steps that HP has written, and links to HP drivers.
But ... since yours does not even power on, there is no way for you to run those diagnostics.
Given that this is a new HP model, it is likely STILL under the original HP warranty. You should contact HP Customer Support directly to see about returning it under the warranty for HP diagnosis and repair. If they can't fix it, then you need to explore the options for having it replaced under warranty.
If you live in the US or Canada, contact information is on this page: http://www8.hp.com/us/en/contact-hp/phone-assist.html#section1
If you live elsewhere, contact information is on this page: http://www8.hp.com/us/en/contact-hp/ww-contact-us.html
NOTE: After you get through, stay on the line until you are finally able to talk to some one -- it can take a while!
If you have trouble finding a phone number, then try: 1 (800) 474-6836
