You mostly see high CPU usage when an application or process performs CPU-intensive tasks. And when a single application uses a tremendous amount of computer resources, the OS will not have enough to perform even simple tasks. Therefore, the system will feel a lot choppy and laggy.
One such process that may use extreme CPU usage is the PC Doctor Module. The PC Doctor Module runs in the background and detects any problem with OS, which may result in high CPU usage.
Before we get into how to fix the high CPU usage, let us get some knowledge about the PC Doctor Module itself.
What Does the PC Doctor Module Do?
PC Doctor module runs as a part of Dell SupportAssist. The Dell SupportAssist comes pre-installed on all Dell computers and laptops. The SupportAssist has administrator-level access to the Operating System, which optimizes settings to improve performance, updates drivers, and troubleshoots any issues with the OS.
The PC Doctor Module runs within Dell SupportAssists, scans the OS for any issues, and sends the report to Dell Technical Support. Scanning the OS for any issues or checking if any of the drivers need an update may take high CPU usage for a certain time. But if the process constantly takes up extreme CPU, memory, and GPU usage, it can be a cause for concern.
Why Does My PC Doctor Module Have High CPU?
PC-Doctor module running in the background usually means that Dell SupportAssist is active. It is highly likely that the process is updating the driver or the OS. Moreover, it also troubleshoots any errors and sends the data from the troubleshoot to Dell’s support.
