Since it is a "new" computer I would just do a factory reset. Seeing that it came with windows 8, I am assuming that it is a 'newer' model. Typically all newer laptops dont come with a recovery disk anymore, rather they have a secret factory reset partition.
**** BOTH OPTIONS WILL DELETE ANY PROGRAM / FILES ****
Save anything you want on a flash drive.
**Also write down, take a picture of, use another computer if you are going to follow these steps. Once your computer restarts you wont be able to read anything or google anything until its finished.
Option 1.
Hopefully you do you have the option to factory reset (Personally I dont have HP so I googled it, all laptops have different methods to factory reset)
1. Plug in laptop (dont want it to die during the reset)
2. Hit Start > All Programs > System Recovery > PC Recovery
3. Select PC Recovery then hit Next
4. - Computer should restart dont panic -
5. "Welcome Window" > hit OK
6. Should have a "System Recovery" option
7. Computer should restart a bunch of times and take ~3-4 hours to finish.
Or in the start menu search for "Recovery" or "Recovery Manager"
If you cant find / your computer doesnt have this option:

^ You have to spam the F8, hitting it once doesnt do anything unless you have perfect timing.
Option 2 (Nerdier way) Reformatting your computer via reinstalling OS.
You either need a Windows CD or pirate it and just do a reformat. Its not too complicated but it can be confusing for anything not tech savvy.
Essentially go through the installation process, but say partition HDD.
* Note: from what Ive noticed Windows 7 will install all the necessary drivers (program) e.g. your network card driver, without it = no internet. Assuming 8 will too. But just in case download all necessary drivers and save them on a flash drive.
^ I can help with this if you trust me with your laptop. It should take ~3-5 hours depending on your computer's specs.
** If not you can download TeamViewer which allows someone to control your computer remotely, and hopefully they can solve it.
Good Luck!
