Are you frustrated with your PC’s performance, noticing that it’s always running at 100 CPU usage? This issue can significantly slow down your computer, cause overheating, and lead to system crashes. In this article, we’ll delve into the possible reasons behind this problem and provide you with practical solutions to resolve it.
Introduction to CPU Usage
CPU (Central Processing Unit) usage refers to the amount of time your computer’s processor spends executing instructions. It’s measured as a percentage, with 100% indicating that the CPU is fully utilized. Normally, CPU usage fluctuates depending on the tasks you’re performing, but it should not remain at 100% for an extended period. Prolonged high CPU usage can be a sign of a underlying problem, which, if left unaddressed, can lead to more severe issues.
Causes of High CPU Usage
There are several reasons why your PC might be experiencing high CPU usage. Some of the most common causes include:
High CPU usage can be caused by a variety of factors, including resource-intensive programs, malware infections, outdated drivers, and inefficient system settings. It’s essential to identify the root cause of the issue to apply the correct solution.
