There are still some things you can try. In this article, we’ll show you how to fix high CPU usage at 100%.

1. Reboot PC

If your computer is running slowly and your CPU usage is at 100%, it’s time for a reboot. This will help to clear up any system errors that may be causing the high usage and restore your computer to peak performance. To reboot, simply turn off your computer and wait a few minutes before turning it back on again. Once it’s up and running, you should notice a significant improvement in speed and efficiency. If you’re still seeing high CPU usage after rebooting, there may be a more serious problem that needs to be addressed. However, in most cases, a simple reboot will do the trick.

2. End or Restart Processes that are overloading the CPU

A process is an instance of a computer program that is being executed. Each process has its system resources (CPU and memory) that it uses. Sometimes, a process can use up too much CPU, causing your computer to slow down or even freeze. In this blog post, we’ll show you how to fix high CPU usage caused by processes.

Ending Processes to Fix High CPU Usage

If a process is using up too much CPU, you can end the process to free up resources for other processes. To do this, open the Task Manager and find the process that is using up the most CPU. Then, click on the End Process button.

Restarting Processes to Fix High CPU Usage

If ending a process doesn’t fix the high CPU usage issue, you can try restarting the process. To do this, open the Task Manager and find the process that is using up the most CPU. Then, click on the Restart button. This will kill the process and start it fresh, which can help fix high CPU usage issues.

High CPU usage can be caused by processes that are consuming too many resources. You can fix this issue by ending or restarting processes. If you’re not sure which process is causing the problem, you can try ending or restarting all processes to see if that fixes the issue.

How to remove a virus or malware from your computer

There are a few different ways you can try to remove a virus or malware from your computer. We will go through a few different methods you can try below:

Method 1: Use an antivirus program to scan and remove the virus or malware 

This is the most common and effective method for removing a virus or malware from your computer. Antivirus programs are designed to detect and remove viruses and malware. There are many different antivirus programs out there so make sure to research which one would work best for your situation before downloading one. Once you have chosen and installed an antivirus program, run a full scan of your computer. This may take a while depending on how big your hard drive is but it will be worth it in the end. The antivirus program should be able to detect and remove any virus or malware on your computer.

If this method did not work, don’t worry! There are still a few other methods you can try out.

Method 2: Use System Restore to go back to a date when your computer was not infected  

This method works best if you can remember roughly when your computer got infected with the virus or malware. System Restore goes back to a restore point, which is a saved state of your computer from an earlier date and restores your computer to that state. This will remove any programs or files that were created after that restore point was made, however, so only use this method if you are willing to lose any files or programs that were created after the date of the restore point.

To use this method, follow the below steps:

1) Go to Start > All Programs > Accessories > System Tools > System Restore

2) Choose the “Restore my computer to an earlier time” option and click “Next”

3) Select the most recent restore point from the “On this list, click a restore point” list, and then click “Next”

4) Click “Next” again on the Confirm Restore Point Selection screen  5) Your computer will now restart and go back to the state it was in at the date of the selected restore point. If this does not work, don’t worry! Our computer geeks can sort out viruses in a breeze!
