Hi @Chan61180,

Welcome to The HP Support Community.  

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

I understand you are getting a loud siren from your HP All-in-One 22-dd0016 during startup after a RAM upgrade usually indicates a hardware issue. It might be caused by improperly seated RAM, incompatible memory, or system settings that need adjusting.
 

Steps to Troubleshoot:

Power Down and Unplug:

• Shut down your computer and disconnect it from the power source.

Recheck the RAM Installation:

• Open the back panel of your All-in-One carefully.
• Remove the newly installed RAM module(s).
• Ensure the RAM slots and connectors are free of dust.
• Reinsert the RAM firmly until it clicks into place. Ensure it's oriented correctly (notches should align).

Verify RAM Compatibility:

• Ensure the new RAM matches the system's specifications:
  • DDR4 SDRAM (Check speed and size requirements from your HP manual or support page).
  • Avoid mixing RAM with different speeds or types.
• Use only supported configurations (e.g., single-channel, dual-channel).

Reset the CMOS (Optional):

• Disconnect the power and hold the power button for 15 seconds to discharge any residual power.
• Look for a small CMOS battery on the motherboard; remove it for 5 minutes, then reinstall it. This resets BIOS settings.

Start with One Module:

• If you've installed multiple RAM sticks, try booting with one stick at a time. This helps isolate a faulty module.

Check BIOS Settings:

• If the system powers on without a siren after reseating RAM, access the BIOS/UEFI settings by pressing the appropriate key (e.g., F10, Esc, or Del during startup).
• Check the RAM configuration and ensure it's recognized correctly.

Test Original Configuration:

• Remove the upgraded RAM and boot the system with the original RAM. If the siren stops, the issue is with the new RAM.

Inspect for Physical Damage:

• Check the RAM slots and module pins for damage. Bent pins or debris can cause issues.
