Hi @Joanne710,

Welcome to the HP Support Community.
 

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

I understand your new HP computer's screen has gone black and is flashing something too quickly to read; it could be due to a hardware initialization issue, a BIOS error, or a display driver problem. Here are a few steps you can try:
 

1. Perform a Hard Reset:
   • Turn off the computer.
   • Disconnect the power adapter and remove any external devices (USBs, printers, etc.).
   • Press and hold the Power button for about 15 seconds.
   • Reconnect the power and try turning it on again.
      
2. Check for LED Blink or Beep Codes:
   • If the screen is black but you see blinking lights or hear beeps, your system might be giving a diagnostic code.
   • Count the number of blinks or beeps and refer to this guide:
     👉 HP Notebook PCs - Computer beeps or a light blinks during startup | HP® Support
      
3. Connect to an External Monitor:
   • This helps determine if the issue is with the screen or the system itself.
   • If the external monitor works, the laptop screen might need service.
      
4. BIOS Recovery:
   • If you briefly see a flashing message, it might be a BIOS recovery screen.
   • Try pressing Windows + B (or Windows + V) while holding the Power button for 2–3 seconds, then release the power button but keep holding the keys for a few more seconds.

I hope this helps.

Take care and have a good day.
