Update Drivers If a process is still using too much CPU, try updating your drivers. Drivers are programs that control particular devices connected to your motherboard. Updating your drivers may eliminate compatibility issues or bugs that cause increased CPU usage.
What causes high CPU usage?
Old drivers or flaky pieces of software frequently cause high CPU usage. I recently had a case of unexplained high CPU usage that ended up being caused by a four-year-old Wi-Fi driver that was incompatible with the latest release of Windows 10. A simple driver update fixed the issue completely.
Why is my CPU so hot?
Your PC has fans and other cooling mechanisms to regulate internal temps, because these same heat-producing components are also extremely sensitive to high heat levels. Sustained high CPU usage makes your CPU much hotter than normal, which can cause slow performance, freezes, or crashes.
How do I know if my CPU is high?
Look for the “CPU” column near the top of the Processes tab and click it to order by CPU usage: You can expect high CPU utilization when playing some games, running a video-editing or streaming application, performing an antivirus scan, or juggling many browser tabs.
Why does my CPU temperature fluctuate in Windows 10?
Overclocking is one of the main reasons behind the fluctuations in CPU temperature in Windows 10. When you push your CPU to higher clock speed, the processor works faster and makes the CPU temperature high. You may experience a system crash also if the CPU gets too hot. You should revert the clock settings If you have overclocked your PC.
