Hi @Raymax82,

Welcome to the HP Support Community! 

Thanks for reaching out about your query regarding your PC!

We're thrilled to have the opportunity to assist you and provide a solution.

Try these steps:

Power Cycle the Computer

• Turn off the computer and disconnect all peripherals.
• Unplug the power cord from the computer.
• Press and hold the power button for about 15 seconds. This drains any residual power.
• Plug the power cord back in and attempt to turn on the computer.

Check Power Source

• Ensure the computer is plugged into a working power outlet.
• Test the power outlet with another device to confirm it is providing power.

Check Power Supply Unit (PSU)

• Inspect the PSU for any signs of damage or wear.
• If possible, use a spare or verified working PSU to test the computer.

Reseat Components

• Open the case and ensure all internal components are securely connected.
• Reseat the motherboard connection cables, memory modules, and graphics card.
• Check for any loose or disconnected cables.

Check Memory Modules

• Remove and reseat the RAM memory modules.
• If you have multiple memory modules, try booting with one module at a time to identify if a module is faulty.

Diagnose Blink Codes

• Count the pattern of blinks if the power light is blinking in a specific sequence.
• Refer to the HP blink code guide to identify the error.

I hope this helps.
