HP All-in-one desktop freezes and makes loud buzzing from speaker

[GregPf1]

My HP desktop is now feezing regularly, 1 -2 x / day, requiring a hard restart. When it feezes, there is a loud buzzing noise coming from the speaker. 

I believe this could be a main board fault?

Trouble shooting and diagnostics have so far revealed nothing unusual.

Hi @GregPf1,

Welcome to HP Support Community.

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

The issue you're experiencing with your HP Pavilion 27-inch All-in-One Desktop PC freezing and making a loud buzzing noise could stem from various causes. While a motherboard fault is a possibility, it's also important to consider other potential issues like.

Overheating

• Symptoms: Sudden freezes and buzzing can happen when the CPU or GPU overheats.
• Check: Monitor your system's temperature using software like HWMonitor or Speccy to see if temperatures are unusually high during normal use.

Faulty RAM or Memory Issues

• Symptoms: Faulty or unstable RAM can lead to system crashes and freezing.
• Check: Run a memory diagnostic test, such as Windows Memory Diagnostic, to ensure your RAM is functioning correctly.

Driver Conflicts or Corruption

• Symptoms: Outdated or corrupted drivers (especially sound or graphics drivers) can cause system instability and audio glitches.
• Check: Update your graphics and audio drivers via Device Manager or download the latest versions from HP’s website.

Power Supply Issues

• Symptoms: A failing or insufficient power supply could cause freezing under load.
• Check: Ensure your power supply is stable and provides adequate power to all components.

Corrupt Operating System or Software Conflicts

• Symptoms: Software conflicts or system file corruption can cause freezing and odd behaviors like buzzing.
• Check: Run sfc /scannow in Command Prompt to scan and repair system files, or consider a clean OS reinstall if software corruption is suspected.

Storage (SSD/HDD) Issues

• Symptoms: If the hard drive or SSD has bad sectors or is failing, the system may freeze.
• Check: Run chkdsk to verify the integrity of your storage drive.

BIOS or Firmware Issues

• Symptoms: Outdated BIOS can sometimes cause system instability.
• Check: Ensure your BIOS is updated to the latest version from HP’s support page.

Steps to Troubleshoot:

1. Monitor System Temperatures during use to rule out overheating.
2. Run a Memory Test to detect potential RAM issues.
3. Update Drivers including graphics, audio, and motherboard chipset drivers.
4. Check Event Viewer for logs that may indicate hardware or software errors leading to the freeze.
5. Test with External Speakers or Headphones to rule out any speaker-specific issues.
6. Run Diagnostic Tools: Use HP's built-in diagnostics or download HP Support Assistant to perform a more thorough check.

I hope this helps.

Take care and have a good day.

Hi @GregPf1,

Thank you for your response, 

You've already run tests that didn’t reveal any issues, it suggests a potential problem with hardware, drivers, or system conflicts. Here’s a step-by-step approach to diagnose and potentially resolve the issue.

Check Event Viewer Logs:

• Open Event Viewer by typing Event Viewer in the Start menu and selecting it.
• Go to Windows Logs > System and Application to review the errors and warnings.
• Look for any recurring errors or warnings that might give clues about the underlying issue.

Update Drivers:

• Ensure all drivers are up-to-date, especially for audio, graphics, and chipset.
• Visit the HP support site to download the latest drivers for your specific model.

Check for Windows Updates:

• Go to Settings > Update & Security > Windows Update and ensure your system is fully updated.

Run a Full System Scan:

• Use Windows Defender or any other reputable antivirus software to perform a full system scan for malware or corrupt files.

Check for Hardware Issues:

• RAM: Faulty RAM can cause freezes and buzzing sounds. Use the built-in Windows Memory Diagnostic tool or third-party tools like MemTest86.
• Hard Drive: Run a check on your hard drive for errors using chkdsk. Open Command Prompt as an administrator and run chkdsk /f /r.
• Overheating: Ensure that your desktop is not overheating. Clean any dust from vents and ensure fans are working properly.

Check Audio Settings:

• Go to Settings > System > Sound and ensure that audio drivers are correctly installed and configured.
• Try disabling any audio enhancements or specific sound settings to see if it resolves the issue.

Perform a Clean Boot:

• Perform a clean boot to rule out any third-party applications or services causing the issue.
• Type msconfig in the Start menu, go to the Services tab, check Hide all Microsoft services, and then disable all remaining services. Reboot and check if the issue persists.

Reset or Reinstall Windows:

• If the issue continues and you’ve exhausted other troubleshooting steps, you might consider performing a system reset or clean reinstall of Windows as a last resort.

I hope this helps.

Take care and have a good day.
