Hp Omen 30 L desktop no signal to monitor

[Pippa21]

I installed two optional updates, one for my monitor the other turned out to be a bios update which I think was installed a week ago through the HP assistant. When the computer rebooted I got a black screen and the monitor whet to sleep. I get no signals from the GPU and I've tried another monitor and several cables. I've tried the windows key and B key to get to the recovery and nothing. I'm frustrated as it's only three weeks old.

Hi @Pippa21,

Welcome to the HP Support Community

I understand you are facing an issue with your OMEN 30L Desktop PC GT13-1000a. Not to worry I will help you to get a resolution to resolve the issue.

Crisis BIOS Recovery

1. Turn off the computer, and then connect the power cord.
2. Press and hold the Windows key and the B key at the same time, and then press and hold the Power button for 2 to 3 seconds.

1. Release the Power button but continue pressing the Windows and B keys. You might hear a series of beeps.

• If the HP BIOS Update screen does not display, repeat the previous steps but press the Windows key and the V key. If the screen still does not display, your computer might not support the feature or there is a hard drive issue. Continue to the next section to Recover the BIOS using a USB recovery drive.
• If the Power light turns off, the Power button was held too long. Repeat the previous steps, making sure to hold the Power button for only 2 to 3 seconds.
• If a BIOS recovery message repeatedly displays, continue to the next section to Recover the BIOS using a USB recovery drive.
• If a message that the computer improperly shut down or a boot problem is detected displays, follow the on-screen instructions to resolve the error.
• If Windows starts, update to the latest BIOS version. Go to HP Notebook PCs - Updating the BIOS for more information.
  The HP BIOS Update screen displays and the recovery begins automatically.

I did everything you mentioned but there was no output from the motherboard to the graphics card. The computer has since been replaced under warranty
