Random black screen and fan full speed on Omen 45L

[fv732]

Hello HP Community,

I have an Omen 45L desktop with only one external devices which is a scarlett audio interface. After a few weeks after acquiring the Desktop, I started getting black screens during gaming. The screen goes randomly black and fan go full speed. Sometines also i would have audio stutter /crackling before the crash. The only option is to restart the PC. Frequency of these issues is increasing: it appears in every game now after a few minutes, can happen now while watching youtube. I tried every  solution out there and nothing works. My bios and all drivers up to date. This is really annoying for such an expensive machine: a gaming PC on which you cannot play game !

Is there a way to fix this ?

Thanks a lot.

Hi @fv732,

Welcome to HP Support Community.

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

I'm sorry to hear you're having trouble with your Omen 45L desktop. Random black screens, full-speed fans, and audio stuttering can be quite frustrating, especially with a high-end gaming PC. Here are some detailed troubleshooting steps to address these issues:

**1. Check Hardware Connections

• Power Off: Shut down your PC and unplug it from the power source.
• Open Case: Carefully open the case.
• Reseat RAM: Remove and reinsert the RAM modules. Ensure they are firmly seated in their slots.
• Check GPU: Ensure the graphics card is properly seated and connected. Remove and reseat it if necessary.
• Check Cables: Ensure all internal cables are securely connected, including those from the PSU (Power Supply Unit) to the motherboard and GPU.

**2. Update or Reinstall Drivers

• Download Latest Drivers: Visit the GPU manufacturer’s website (NVIDIA or AMD) to download the latest drivers.
• Clean Install: Use tools like DDU (Display Driver Uninstaller) to completely remove old drivers before installing the new ones.
• Download Latest Drivers: Check for updates for other critical drivers (chipset, audio, etc.) via the HP Support website or the component ' sites.

**3. Check for Overheating

• Use Monitoring Software: Tools like HWMonitor or MSI Afterburner can help you keep track of CPU and GPU temperatures.
• Ensure Proper Cooling: Check that all fans are working properly and that there is no dust buildup blocking airflow.
• Dust Off Components: Use compressed air to clean out dust from fans, vents, and heatsinks.

**4. Test Hardware Components

• Use Windows Memory Diagnostic: Search for “Windows Memory Diagnostic” in the Start menu and run the test.
• Use MemTest86: For a more thorough check, use MemTest86 to test your RAM for errors.
• Run Stress Tests: Use software like FurMark to stress test your GPU and check for stability issues.
• Check SSD/HDD Health: Use tools like CrystalDiskInfo to check the health of your storage devices.

**5. Check for Software Conflicts

• If you have overclocked any components (CPU, GPU, RAM), revert them to their default settings.
• Check for Conflicts: Uninstall any recently installed software or drivers that might be causing conflicts.

**6. BIOS Settings and Update

• Visit HP Support: Check if there is a newer BIOS version available for your Omen 45L and follow the instructions to update it.
• Enter BIOS: Restart your PC and enter BIOS setup (usually by pressing F2, F10, DEL, or ESC during boot).
• Load Default Settings: Find the option to load default settings or optimized defaults.

I hope this helps.

Take care and have a good day.
