Issue: How to fix Google Chrome high CPU usage in Windows?
Hello. I noticed that Google Chrome uses high amounts of CPU on my Windows PC even when I have just a couple of tabs open. Any way to fix this issue?
High CPU usage is a recurring problem that periodically tarnishes Google Chrome's reputation as a popular and effective browser. While Chrome is known for its relatively higher consumption of CPU and memory compared to other browsers, the concern arises when the usage surpasses the typical 70-80% threshold or remains elevated even with a moderate number of tabs open. A user's workflow may be greatly impacted by this high CPU usage, which can result in poor performance, sluggish reaction times, and a generally impaired browsing experience.
This problem has multiple contributing factors. Installed extensions, which are frequently meant to improve browsing performance, may occasionally be the cause of elevated CPU usage. Furthermore, malware on a user's computer may make the issue worse, impacting not just Chrome's functionality but also presenting a wider risk to the system. Using Chrome in a virtual machine might increase CPU usage even more, and corrupt Chrome files might also play a role.
High CPU utilization has more negative effects than just being inconvenient. Users might notice a general slowdown in the speed of their system, which would affect their ability to multitask and interfere with other apps running smoothly. In extreme circumstances, it may result in system instability and crashes, interfering with work and possibly erasing data.
An approach that is strategic is needed to address the problem. To get started, users should make sure that Chrome's files are intact, do comprehensive malware scans, and identify and disable any dangerous extensions. In cases where high CPU usage persists, especially in virtual machine scenarios, optimizing the virtual environment may be necessary.
