![]() This can happen as a result of issues with software on your computer: For example, you may have forgotten to update key software programs on your device, or you may even have malware on your computer that you are unaware of.Īdditionally, high CPU usage can also happen as a result of hardware issues. However, there are many other factors that can also cause high CPU usage, even when your computer is idle, which makes the problem more difficult to solve. ![]() In the Task Manager, you’ll be able to identify which programs have the highest CPU levels. If this is the case, closing these apps should reduce your CPU usage. One of the most common reasons for high CPU usage is running a resource-heavy program on your computer or running too many apps at once. There are a variety of different factors that can cause this problem. In order to fix the problem, you’ll first need to determine why you have high CPU usage in the first place. It’s also worth investigating if your CPU is higher than 30% while idle or running basic programs like a web browser with just a few tabs open. While this isn’t necessarily a problem on its own, it can result in issues down the road if you need to run other programs simultaneously. Some programs will result in higher CPU usage: For example, complex video games often result in a much higher CPU usage. Most PCs have a range of 1-10% CPU while idle and 10-30% while running basic tasks. On a PC, you can check the CPU usage directly in the task manager, while on a Mac, you’ll be able to do so using the Activity Monitor. It’s easy to check your current CPU usage on most computers. At a certain point, however, the data and instructions requested by computer programs may become difficult for the CPU to handle at once, which can cause problems. Each program on the computer provides the CPU with pieces of data and instructions for how to process it.ĬPUs are designed to process a very high volume of data and instruction input at once. Without the CPU, the other components in your computer would not work properly. The CPU serves as your computer’s brain, processing input and providing instructions for all other components of the computer.
