What causes high disk and CPU usage?

There are many possible causes for high disk and CPU usage. One common cause is a process or application that is stuck in a loop or is running continuously. This can happen if an application is not programmed properly, or if there is a problem with the application. Another common cause is a virus or other malware that is running on the computer. This can cause the computer to use a lot of resources to try to remove the malware.

How to fix high disk and CPU usage

If you’re seeing high disk and CPU usage on your Windows computer, it could be due to the “host process for Windows services” (also known as “svchost.exe”). This process is responsible for running various system services, and can sometimes use a lot of resources.

There are a few things you can do to try and fix the issue:

1. Restart your computer. This will often fix the problem, as svchost.exe will be restarted and won’t have a chance to use up all your resources.

2. Update your drivers. Outdated drivers can sometimes cause issues with svchost.exe.

3. Run a virus scan. Sometimes, high resource usage can be caused by malware.

4. Disable certain services. Some services that run under svchost.exe might not be necessary, and you can disable them to free up resources.

If you’re still seeing high CPU and disk usage after trying these steps, you may need to contact a technician for further assistance.
