Thank you for posting back. 

To ensure this isn't a hardware malfunction, I suggest running an extensive system test. The Extensive Test will take 2 hours or more. 

If the HP PC Hardware Diagnostics for Windows app is not available on your computer, download the latest version from the HP Hardware Diagnostics website.
1. In Windows, search for and open the HP PC Hardware Diagnostics Windows app.
2. On the main menu, click System Tests.
3. Click the System Extensive Test tab.
4. Click Run once.

Hope this helps! Keep me posted for further assistance.
