Hi @ChrisSooley,
Welcome to the HP Support Community.
I'd like to help!
I recommend you follow the below steps and check whether the issue is resolved.
1. Turn off the computer.
2. Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers.
3. Unplug the power cable from the computer.
4. With the power cord unplugged, press and hold the Power button for about 15 seconds to drain any residual electrical charge from the capacitors.
5. Connect the power cable, but do not connect any of the peripheral devices.
6. Press the Power button to turn on the computer.
7. If a startup menu opens, use the arrow keys to select Start Windows Normally, and then press the Enter key.
8. After Windows opens, reconnect each peripheral device that was disconnected, one device at a time, until all devices are reconnected.
