Computer not starting up

[ojbwvpkW533]

I did a diagnostic check the day before to do a check up on the stability of my computer, everything appeared to be fine so i turned my computer off for the rest of the day. The next day i boot up my computer to find that it wanted to update the BIOS, so i started the BIOS update, however, i did not turn off the computer and I had no power outage, yet when I returned the computer was running but it only had a black screen

Hi @ojbwvpkW533,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

It sounds like your computer might be experiencing a critical issue following a BIOS update. Here’s what you can try to troubleshoot and hopefully resolve the issue:

1. Perform a Hard Reset

Sometimes, a hard reset can resolve issues with black screens or unresponsive systems.

1. Turn off your computer completely. If it's unresponsive, press and hold the power button until it shuts down.
2. Disconnect all external devices such as USB drives, printers, and external monitors.
3. Remove the power cable from the computer.
4. Press and hold the power button for 15-20 seconds to discharge any residual power.
5. Reconnect the power cable and try turning on your computer.

2. Boot into BIOS/UEFI Settings

If your computer shows any signs of life (lights, sounds, etc.) but still displays a black screen, try accessing the BIOS/UEFI settings.

1. Restart your computer.
2. Repeatedly press the BIOS/UEFI access key during startup. This key is often displayed on the screen during startup (e.g., F2, Del, Esc).
3. Once in BIOS/UEFI settings, check if you can navigate through the menus. This confirms that your computer's basic hardware components are functioning.

3. Clear CMOS (BIOS Reset)

Resetting the CMOS can sometimes resolve issues caused by a failed BIOS update.

1. Turn off your computer and disconnect the power cable.
2. Locate the CMOS battery on your motherboard (it looks like a watch battery).
3. Remove the CMOS battery for about 10-15 minutes.
4. Reinsert the CMOS battery and reconnect the power cable.
5. Try powering on your computer to see if the issue is resolved.

I hope this helps.

Take care and have a good day.

Hello rachel,

thank you for answering my question, however, I am unable to reach your step 2 of reaching the bios/ UEFI I have done some research and I think that the update had somehow messed with the connection between my motherboard, and my graphics card, which is an rtx 3060. I appreciate your service and I will continue to try your recommendations until I find a result.
