Then yes, call HP Total Care at 800-474-6836. Let the representative know you've already done a recovery (reinstalled Windows) and the issue is still happening. This is assuming you bought it in the U.S. and are still in the U.S. because that's the U.S. support number. If you (or anyone else coming across this post) bought the computer in a different country and you're in that country still, you can find the support number on this page.
The phone support agent can set up a repair for you and explain how the repair works. Let me know if you run into any issues there. :)
