Hi @Kmoss,

Welcome to HP Support Community.

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

It sounds like your HP PC is experiencing overheating issues, which could be due to a malfunctioning cooling fan or another related component. Here’s a step-by-step guide to troubleshoot the issue.

Check the Cooling Fan:

• Open your PC case (ensure it’s powered off and unplugged).
• Inspect the cooling fan for dust buildup or obstruction. Clean the fan and surrounding area using compressed air if needed.
• Ensure the fan is securely connected to the motherboard and is spinning correctly when the PC is powered on.

Inspect the Heat Sink:

• Ensure that the heat sink is properly seated on the CPU and that thermal paste is adequately applied.
• If you recently reassembled the PC or changed components, it might be worth reapplying thermal paste.

Verify Fan Settings:

• Enter the BIOS/UEFI settings during startup (usually by pressing F2, F10, or Delete).
• Check the hardware monitoring section to ensure the fan speeds are being detected correctly and adjust fan settings if necessary.

Update Drivers and BIOS:

• Make sure your motherboard and fan drivers are up-to-date. Visit the HP website or use HP Support Assistant to get the latest drivers.
• Check for BIOS updates that might address cooling or hardware issues.

Check for Overheating:

• Use software tools like HWMonitor or SpeedFan to check temperatures and fan speeds.
• If temperatures are abnormally high, it could indicate an issue with cooling or airflow within the case.

Test with Minimal Components:

• If the problem persists, test the system with minimal components (e.g., one stick of RAM, no additional peripherals) to rule out issues with other hardware.

Overheating can cause unexpected shutdowns and glitches, so addressing cooling issues should help stabilize your system.

I hope this helps.

Take care and have a good day.
