When your computer’s CPU usage is really high on Windows 10 or older versions, it might be because of a few things like heavy tasks, too much heat inside, or even viruses. If your computer is always using 90% to 100% of the CPU, here are some reasons why:

1. Your PC is working hard

If your computer is doing a lot of tasks at once, like running several programs or processing big files, it can make your CPU work really hard. This can lead to high CPU usage.

2. Your PC fans aren’t cooling down your CPU

Your computer has fans to keep the CPU cool. If these fans aren’t working properly or if there’s too much dust inside your computer, your CPU can get too hot, causing high CPU usage.

3. You’ve got a malware infection

Malware, like viruses or spyware, can infect your computer and make it do things without your permission. Some malware can make your CPU work harder than it should, leading to high CPU usage.

4. Your drivers or other software are outdated

Drivers are like software that help your computer’s hardware work properly. If they need to be updated or fixed, they can cause your CPU to use more power than it needs to, resulting in high CPU usage.

5. You have too many apps open at once

If you have lots of programs open on your computer at the same time, each one can use up some of your CPU’s power. If you have too many open, it can overload your CPU and cause high CPU usage.

6. A specific app is causing the issue

Sometimes, one particular program or app on your computer can use up a lot of CPU power. This could be because the app is poorly made or has a bug. Identifying and closing the problematic app can help reduce CPU usage.

Factors Contributing to CPU Running at 100%:

Several factors can contribute to a CPU operating at maximum capacity:

  • Software Issues: More efficient or well-optimized software can be needed to maintain CPU resources, leading to high usage.
  • Hardware Issues: Faulty hardware components, such as a malfunctioning cooling system or inadequate power supply, can result in overheating and increased CPU workload.
  • Background Processes: Background applications and services running on the system may consume CPU resources, causing it to operate at full capacity.
