Does the store that sold it to you offer a 30-day warranty, or a "30 day no questions asked" return policy?
Your HP computer also comes with a warranty. Contact HP Support.
Note that it is highly likely that the disk-drive, containing your files, is perfectly fine.
A computer technician can remove the disk-drive, connect it to a different computer, and copy your files.
Do this, before you ship the computer to HP,, for repair.
