For example, an outdated graphics card driver can cause the computer to run slowly or crash when running graphics-intensive applications, such as games or video editing software.

To identify outdated or corrupted drivers, users can use the Device Manager tool in Windows. The Device Manager can show which hardware devices are experiencing issues and which drivers may need to be updated or repaired.

Overheating and insufficient ventilation

Overheating occurs when the computer's internal temperature rises above normal operating levels. This can be caused by several factors, such as blocked air vents, a malfunctioning fan, or running resource-intensive applications for extended periods.

When a computer overheats, the CPU can be forced to slow down or shut down to prevent damage. This can result in high CPU usage and poor performance. Insufficient ventilation can also cause high CPU usage and poor performance by preventing heat from dissipating from the computer effectively.

To prevent overheating and ensure proper ventilation, users should ensure that the computer is placed on a flat surface with sufficient space for air to circulate. Users should also ensure that the air vents are not blocked by dust or other debris and that the fan functions correctly.

Users can also monitor the internal temperature of the computer using software tools such as HWMonitor or Core Temp. These tools can provide real-time temperature readings for various components, including the CPU and GPU.

If the computer is experiencing overheating issues, users can take several steps to reduce the temperature and improve performance. These include reducing the workload on the CPU by closing resource-intensive applications, cleaning the air vents and fan, and using a cooling pad or external fan to improve ventilation.

Hardware issues

Hardware issues can cause high CPU usage and poor computer performance due to faulty or damaged hardware components. The computer may experience crashes, freezes, and high CPU usage when hardware components malfunction. Users can identify hardware issues by running diagnostic tests on their computers. Diagnostic tests can provide useful information about which hardware component is causing the issue and whether it needs to be repaired or replaced.

Users can perform regular maintenance and upgrade components to prevent hardware issues. Adding more RAM or upgrading to a solid-state drive (SSD) can help improve performance and prevent issues caused by outdated or insufficient hardware.
