Hi @Jeremy124,

Welcome to the HP Support Community. 

I'd be glad to help you! 

It sounds like your OMEN 30L is having trouble powering on, with flashing lights and sounds followed by an immediate shutdown. This could be related to hardware, power supply, or internal component issues. Let's go through the probing questions and troubleshooting steps to help identify and resolve the issue.

• Have you made any recent hardware changes or upgrades (e.g., new RAM, GPU, storage devices) to the OMEN 30L?
• Did the issue start after any software updates or new installations?
• Are you using the original power cable and power supply that came with the OMEN 30L?
• Have you experienced any power outages, surges, or fluctuations recently?
• Do you see any specific error messages, beep codes, or LED error patterns on the motherboard when attempting to boot?
• Does the PC shut down immediately after powering on, or does it stay on for a few seconds?
• Are any external devices (USBs, external drives, peripherals) connected when you try to power on the PC?
• Have you tried disconnecting all peripherals to see if the issue persists?
• Have you noticed the system running hot or experiencing unusual fan noise before this issue started?
• When was the last time you cleaned the inside of your PC, including fans and heat sinks?

Also, perform the steps below.

Perform a Hard Reset:

• Disconnect the power cable from the OMEN 30L.
• Press and hold the Power button for 15 seconds to discharge any residual power.
• Reconnect the power cable and try powering on the PC.

Check Power Supply Connections:

• Ensure all power connections from the power supply to the motherboard, CPU, and GPU are secure.
• Check for any visible damage or loose cables inside the PC.

Test with Minimal Configuration:

• Disconnect all external peripherals (keyboard, mouse, USB devices, etc.).
• Open the case and remove any non-essential components (extra RAM sticks, additional hard drives, external graphics cards if there's onboard graphics available).
• Try powering on with only the essential components (CPU, one stick of RAM, motherboard, and power supply).

Please find the remaining steps in the next post.

Hope this helps! Keep me posted for further assistance

Hi @Jeremy124,

Please find the remaining steps below. 

Inspect for Beep Codes or LED Indicators:

• If your motherboard has diagnostic LEDs or a display, check the codes displayed during startup.
• Refer to the motherboard manual for the meaning of any beep codes or LED error patterns.

Check for Overheating or Short-Circuits:

• Inspect the PC for any signs of overheating or burning smells.
• Ensure that no components or cables are causing a short-circuit, such as loose screws or bent pins.

Test the Power Supply:

• If possible, test the power supply with another known working system or a PSU tester.
• Check that the power supply unit (PSU) fan is spinning when attempting to power on.

Reseat Internal Components:

• Reseat the RAM modules, GPU, and any other internal components to ensure proper connection.
• Check for dust or debris that may be causing connection issues.

Clear CMOS/Reset BIOS:

• Turn off the power and disconnect from the outlet.
• Locate the CMOS battery on the motherboard, remove it for about 5 minutes, then reinsert it.
• Alternatively, use the CMOS reset jumper if available.

Check for Firmware Updates:

• If you can access the system for a short period, try updating the BIOS/UEFI firmware from the HP support site.

Check for Faulty Hardware:

• If the system still fails to boot, the issue could be with a specific component like the motherboard, RAM, or CPU.
• Consider testing components individually in another compatible system if available, or consult with a professional technician.

If these steps don't resolve the issue, it's possible that there might be a hardware fault.

In this case, I recommend you contact phone support for repair or service options.  

Hope this helps! Keep me posted for further assistance
