I have the HP Spectre x360-13-ap0013dx. I just got it less then three months ago brand new from best buy. Recently it started freezing out of no where at random times. I took it to best buy and they said they couldn't find anything that was wrong but I need this computer for college and I don't really want to spend extra money on a laptop that was brand new to fix this

Hi
First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.
Rinse and Repeat

NOW begin checking/testing/proving the Hardware is fit for purpose.
Power on your PC, press ESC (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).
AND/OR
HOW DO I USE DIAGNOSTICS?

HP PC Hardware Diagnostics Windows is a Windows-based utility that allows you to run diagnostic tests to determine if the computer hardware is functioning properly. The tool runs within the Windows operating system in order to diagnose hardware failures. HP PC Hardware Diagnostics Windows comes pre-installed on new HP computers, but if not on yours, download here:- http://ftp.hp.com/pub/softpaq/sp93001-93500/sp93457.exe

I have tried the diagnostic texts and I’ve even done the long one and I still have the same issue

Hi

If he hardware passes, then it is software that is the next suspect.

Re-Install drivers.
