4 Causes Why Does CPU Usage Go Down In Task Manager

4 Causes Why Does CPU Usage Go Down In Task Manager | cpugpunerds.com

Different CPUs have different clock speeds, and each CPU’s usage depends on its specific clock speed. 

The CPU performs one major function, which is the transfer of given instructions or data from one hardware component to another. That is why it is also known as the “brain” of a computer. Your computer will not function and cannot complete tasks if the CPU is absent.

CPU usage depends on the running tasks and processes. Some users report that their CPU usage decreases when opening the Task Manager. We will discuss why CPU usage is so high until the user opens the Task Manager and the causes of these fluctuations.

4 Causes Why Does CPU Usage Go Down When You Open Task Manager

The major reasons are task manager adjustments, virus or malware infection, cryptocurrency software, and bad sectors. All these reasons can cause fluctuations and low CPU usage. Some of them are huge problems, and some of them are just regular task manager functions.

1. The Task Manager Is Just Adjusting Itself

The Task Manager will make the necessary adjustments to ensure the system operates effectively without hiccups. It is possible to adjust the priority of a process or program using Task Manager if that process or program is using up an excessive amount of resources. It will allow other programs to receive the resources that they require. 

In addition, the Task Manager can terminate either unnecessary or malicious processes, free up memory, and monitor the system’s performance.

2. A Virus Has Infected Your Computer

If a virus has infected your computer, the Task Manager’s CPU usage can fluctuate because it may be stealing resources from the CPU to run its malicious activities. It can cause the CPU to get too busy, slowing things down and making the CPU less useful.

Moreover, this virus can be hidden, and whenever you open your task manager, it will turn off your presence in the processes. As a result, your CPU usage in the task manager goes down. That is why your CPU usage goes down automatically when you open your task manager.

3. Cryptocurrency Mining Software Is Installed On Your Computer

Task Manager CPU usage will fluctuate if you use cryptocurrency mining software because it is designed to constantly take up as much computing power as possible to mine for cryptocurrency. It can make the CPU usage go up and down as the software works to get the most out of its mining power.

Also, mining software is often made to run in the background, making it hard to find or keep track of what it is doing. If you use any cryptocurrency application or software, you might face this issue in your task manager.

4. A Bad Sector Has Taken Control Of Your Computer

A bad sector on your hard drive can cause your computer’s processing speed to fluctuate as the CPU works harder to access and retrieve data from the bad sector. The bad sector may also slow down the performance of other applications, which may result in inconsistent CPU utilization.

You can eliminate these bad sectors by using a check disk, turning off automatic fixes, or using disk repairing software.

3 Ways To Stabilize CPU Usage

1. Run an SFC Scan

The SFC scan checks the system for damaged or corrupted files. These methods are capable of finding and fixing these files. System files are not easy to detect using any other method. So, first of all, run an SFC scan on your PC to detect faulty system files.

To run the SFC scan, open the command prompt by typing “cmd” in the start menu search. Run the command prompt as an administrator. It gives CMD the administrative privileges to execute commands.

Once in CMD, type “SFC /scannow” and hit enter. It will start executing the command. It will take a second, and all your boot and system files will be repaired automatically.

2. Use Process Explorer To Find Hidden Software

Microsoft Process Explorer is a free tool from Microsoft that provides detailed information about the processes and programs running on your computer. It can be used to find and stop malicious processes, monitor the system running, and examine how the CPU and memory are used. 

Sometimes, hidden software and applications run in the background, and our task manager can also not detect them. These applications or software could be potential malware viruses. You must download Microsoft’s “Process Explorer” app to kill suspicious applications.

Now, install and open the application. The Explorer’s best feature displays which applications use most of your computer’s processing power.

Open the application; now scroll left in the processes bar till you find any unknown applications or processes. Right-click on the process and select “Kill Process” from the file menu to eliminate the process. Delete the process (file/application) from the app data folder.

Type “%appdata% in this PC locator bar, then hit enter. Here, you will find the unknown application folder. Select it and press “Shift + Del.” It will delete the complete folder with its files.

3. Clean Up System Files

The Clean Up System Files feature in Windows 10 allows users to remove unnecessary system files, such as temporary files, old system logs, and other files that are no longer needed. It can free up disk space and reduce CPU usage. 

It can also help to protect user privacy by deleting files that have been downloaded from the internet or that have been left behind by uninstalled programs. To clean up the system, write “Disk Cleanup” and open the app from the start menu.

Now select the derive and press OK. In the final window, select the system options you want to clean and press “cleanup system files.” It will remove all unnecessary files and lessen your CPU burden.

Why Is CPU Usage High?

It could be due to a virus or malware, a lack of adequate RAM, or a poorly designed application causing a bottleneck in the system. It could also be due to a high number of applications running at the same time or a highly intensive task like video editing or rendering.

High CPU usage can be cured by identifying and removing the cause of the issue. Start by running a virus scan to ensure your system is not infected. If there is no virus, check your RAM and ensure it is adequate for your applications. 

You can also try turning off unnecessary applications or processes running in the background. If the issue is due to an intensive task, try to break it up into smaller tasks or use a more efficient application. 

Additionally, ensure your system is updated with the latest drivers and operating system updates. If the issue persists, consider upgrading the components of your system.

Conclusion

CPU usage is an important factor to consider when optimizing your computer’s performance. High CPU usage can cause your computer to slow down, freeze, or even crash. The CPU usage can fluctuate when the Task Manager is opened for various reasons. 

The most common causes for this fluctuation are task manager adjustments, virus or malware infection, cryptocurrency software, and bad sectors. Fortunately, some steps can be taken to help stabilize CPU usage and get the most out of your computer. Running an SFC Scan and using Process Explorer to find and eliminate hidden malicious software can help reduce CPU usage. 

Cleaning up system files can also free up disk space and reduce CPU usage. Finally, if the issue persists, consider upgrading the components of your system. By following these steps, you can ensure that your computer is running at its optimal performance.
