Hi@CobraTrucking,

Thanks for taking an interest in the HP Support Forums! After reading your post I see that you are getting a "Black screen" upon starting up . I would like to help you out with this issue today.

Step one: Perform a hard reset

If your computer suddenly fails to boot properly, you should perform a hard reset.

1. Disconnect all peripheral devices and remove all USB devices and media cards. You want to test the computer not the accessories!

2. Disconnect the AC power adapter, remove the battery, and then press and hold the power button for at least 15 seconds.

3. Reconnect the AC power adapter (but do not connect the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a disk drive and fan turning.

Step two:Attempt a BIOS Recovery

Step three:Run the System Diagnostics tests

Let me know if those steps worked for you. If they did, that’s awesome!

Tried all those steps. This is an all in one desktop, there is no battery to remove. Can't run system diagnostics when there is nothing on screen

Hi @CobraTrucking,

I read your response and reviewed it. Thanks for trying the troubleshooting steps.

Now if you've done a hard reset and it still does not work and there is no display, then there is a hardware issue with the computer. Please contact HP phone support to get the unit serviced. If the unit is under warranty, repair services should be covered by the manufacturer’s warranty. You could look up the unit’s warranty by visiting this link: http://support.hp.com/gb-en/checkwarranty/  and select the country of purchase and follow the on-screen instructions.
