Computer won’t power on, beeping occurs.

[MrUnknowing]

I recently bought a hp omen 870-244 and have had it for about a month. It started though when I was playing helldivers when the screen froze. I then powered off the computer when something weird happened. My computer would power on then power off as if in a loop. I looked online and reset the cmos battery and tested the ram one at a time. The computer doesn’t loop when powered on anymore but now it will beep - - - . . and show no display. I’ve done research and even bought new ram and reseated them but it still won’t fix. What should I do?

Hi @MrUnknowing,

Welcome to the HP Support Community.
 

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

We understand how concerning it is when your HP OMEN 870-244 Desktop PC fails to boot and emits a beep code. Based on your description, three long beeps followed by two short beeps (3-2...), we can confirm that this is a memory (RAM) failure code.

What the Beep Code Means

The 3 long, 2 short beep pattern is HP’s diagnostic indicator for a memory initialization failure. This means the system is unable to properly detect or initialize the installed RAM during POST (Power-On Self-Test).

1. Power Reset the System

• Unplug the power cable.
• Press and hold the power button for 15 seconds.
• Reconnect the power and try to boot.

2. Reseat the Memory Modules

• Power off and unplug the PC.
• Open the side panel.
• Remove each RAM module and gently clean the gold contacts with a soft, lint-free cloth.
• Reinsert the modules firmly into their slots until they click into place.

3. Test One Module at a Time

• If you have multiple RAM sticks: 
  • Insert one stick at a time into DIMM slot 1.
  • Try booting the system with each stick individually.
  • This helps identify if one module is faulty.

4. Try Known-Good RAM

• If available, test with a compatible, known-working DDR4 RAM module.
• Refer to your motherboard manual for supported specifications.

5. Clear CMOS Again

• Disconnect power.
• Remove the CMOS battery for 5 minutes.
• Reinsert the battery and try booting again.

I hope this helps.

Take care and have an amazing day!
