@12345spiros, 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 a cooling fan issue, which can lead to startup warnings and potential overheating. Here are some steps you can take to troubleshoot and resolve this problem:
1. Cleaning the Fan
- Turn off your PC and disconnect the power.
- Remove the battery (if it's a laptop) and unscrew the bottom panel to access the fan.
- Clean the fan using compressed air or a soft brush to remove dust and debris.
2. Checking for Obstructions
- Ensure there are no stickers, tape, or wires obstructing the fan's rotation.
- Reconnect the fan and test it to see if it spins freely.
3. Updating BIOS
- Sometimes, a BIOS update can resolve fan-related issues. Visit the HP Support website and download the latest BIOS update for your model.
4. Running Diagnostics
- Restart your PC and press F2 repeatedly to enter the HP PC Hardware Diagnostics menu.
- Run the System Tests to check for hardware failures.
5. Replacing the Fan
- If cleaning and diagnostics don't resolve the issue, you might need to replace the fan.
