OMEN 30L Desktop PC
This is my Pc, can someone tell me what is defect in my pc if all my ports are not working, i have tried everything (cmos reset, old cpu new cpu, only with 1 ram, different slots for ram) but nothing worked for me so my guess is that maybe my Pcle or Vrms broke or something in the Southbridge. So i had rlly hard fps drops, i always have but they were super strong today like 1-10Fps and then i restarted pc and boom my fans my pc starts all good but nothing connects . Please someone tell me whats wrong.

Hi @Niki1231,

Welcome to the HP Support Community.
 

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

Thank you for reaching out to HP Support regarding your OMEN 30L Desktop PC. We understand how concerning it can be when your system powers on but none of the ports (USB, display, etc.) respond, especially following severe FPS drops and a system restart.

Symptoms You Described

• Sudden extreme FPS drops before failure.
• After restart: no display, no USB power, but fans and lights turn on.
• You've already tried: CMOS reset, CPU swap, RAM slot testing.

🛠️ Steps that you Can Try  

1. BIOS Recovery Attempt:

• Shut down the computer, keep the USB keyboard and Mouse plugged in.
• Hold down the Windows and B buttons together while the computer is still turned off. 
• Turn on the computer and continue to hold the Windows and B buttons until a BIOS Recovery screen appears. 
• Follow the on-screen instructions and click on OK.
  
  Test with Another PSU:
• If you have access to another PSU, test it to rule out power delivery issues.
  
   

2. Remove GPU and Use Integrated Graphics (if available):

• Some OMEN 30L models have integrated graphics. Try removing the GPU and connecting your monitor to the motherboard’s HDMI/DP port.
  
   

3. Inspect the Motherboard for Damage:

• Look for burnt components, bulging capacitors, or discolouration near the VRMs or chipset.

I hope this helps.

Take care and have a good day.
