Overheating after some windows 10 updates and CPU fan runs at high speed

We appreciate the update that you have provided. Your system may be overheating due to dusts or debris that weigh down the cooling fan. Kindly check if there are any blockages to the exhaust vent of your computer as this may heavily affect the cooling fan performance.

Since the high CPU usage is not observed in Safe Mode, it shows us that the problem is not caused by the default drivers and basic settings of Windows. With that note, there might be drivers in your system that require to be updated. We suggest that you check if there are driver updates that are available for your computer. Here's how to check for driver updates through Windows Update:

1. Select the Start button, then select Settings > Update & security > Windows Update.
2. Select Check for updates.
3. If there are updates waiting to be installed, kindly install them.
4. After installing the updates, restart your computer and see if the high CPU usage is still exhibited.

If after installing the update, or if there are no updates, there might be unwanted malicious software that could have affected your system. Often times, these malicious software could cause your PC to perform unusually, and could put a lot of stress to your system. Kindly check for unwanted malicious software through your preferred antivirus program if there are any signs of infection on your computer.

If you find that there are no signs of infection, it is possible that there are corrupted Windows system files. The Deployment Image Service and Management tool (DISM) is a utility in Windows that scans for corrupted Windows system files. If it finds a problem, it would replace the problematic system files from a cached version that's on your PC. Here's how to run the DISM utility:

1. Press the Start button, then type command prompt, then right-click Command Prompt, and select Run as administrator. If you are prompted to enter a password or confirmation, enter the password or provide confirmation.
2. At the command prompt, type the following command and press Enter:
   • dism.exe /Online /Cleanup-image /Restorehealth
     • Kindly take note of the spaces between the command.
3. If DISM finds corrupted files and replaces them, restart your PC and see if that improves the system.

Note: You must be connected to the Internet to use DISM, and it might take several minutes to finish.

If DISM can't replace the files, the System File Checker(SFC) tool could check your system for corrupted files then download and replace the files through Windows Update. Here's how to run the System File Checker tool:

1. Press the Start button, then type command prompt, then right-click Command Prompt, and select Run as administrator. If you are prompted to enter a password or confirmation, enter the password or provide confirmation.
2. At the command prompt, type the following command and press Enter:
   • sfc /scannow
     • Kindly take note of the space between.
     • Note: Scanning would take a few minutes.
3. If SFC finds corrupted files and replaces them, restart your PC and see if the problems persist.

If the above steps does not alleviate the problem, do not hesitate to post back to us.

Hi,

Thanks a lot for the reply.

Well, I tried to figure out the resource consuming tasks using task manager. Even when system is idle (without any applications started by user) I found CPU usage to be around 32% and this usage is mostly due to "Service Host: Local Service (No Network)" and "Service Host: Local Service". See screenshot below. I know for sure this is the reason for my system heating issue. Please, help.

Hi,

Yeah, the Clean Boot didn't help. Also I tried Safe Mode and at this stage CPU usage remains less than 1% (obvious reasons) without any apps running and this is quite ideal and previously, before the installation of recent updates my system used to run just like this (at idle conditions- CPU usage < 10%). I don't know what to do.

Hi,

A service running in the background may be consuming the majority of your computer's resources that is why your computer is overheating. We recommend that you check access the Task Manager to see the resource usage of your computer. If the resource usage is high, check the list of processes to see what program or service that is causing the issue. You can also perform a clean boot to see if your computer will overheat while your third party services are disabled.

Upon checking the model of your computer using its support website, the drivers of your device are only compatible up to Windows 7. If it's still the same after checking the processes and performing clean boot, there can be a compatibility issue between your device and Windows 10 that is why it is overheating. We recommend that you contact the Original Equipment Manufacturer (OEM) so that you can check if there are updates available for the drivers of your device which are compatible with Windows 10.

If you still have any questions, kindly reply to this thread.

Hello,

As Argel Obm cited, a service that is running in the background may be consuming the majority of your computer's resources that is why your computer is overheating. Since you have figured out what these services are through task manager, there might be software conflicts that are occurring in your system that cause these services to take up a lot of your memory and may cause overheating to your computer. May we know if you have attempted to perform a clean boot of Windows as suggested by Argel Obm and see if the problem is exhibited there? This is for us to know and to proceed in troubleshooting the problem further.

We look forward to your response.
