You should not be having problems like this with a new PC!
You paid for free HP Tech Support as part of the warranty coverage, so you might as well make use of it.
Unfortunately, we are NOT HP Tech Support and we have no way to diagnose or repair your PC, so while this PC is still under warranty, you should contact HP Customer Support directly to have them put you in touch with HP Technical Support to see what they can do about troubleshooting and repairing your machine remotely.
I did this recently and the HP Tech was able to remotely access my PC from the Internet to check out the problems.
