Your Dell computer can overheat because of insufficient air flow due to dust or debris blocking the air vents, exhaust ports, or a clogged fan. An overheating computer can intermittently restart, shutdown, or experience performance issues. Eventually excessive heat can damage the internal components.
When the computer overheats, you may experience symptoms such as:
The most common reason for an overheating computer is dust buildup on the fans or air vents. Reduce the heat inside the computer to improve the system performance and prevent any damage to the internal components.
Follow the troubleshooting steps mentioned below in the sequence to resolve overheating, thermal, or intermittent shutdown issues.

It is important to keep dust from accumulating in the computer and provide adequate ventilation to help reduce heat. Lint and dust accumulation prevents the air from flowing around the cooling fins and causes the fan to work harder.
Blocked air vents can cause serious performance issues by restricting airflow. This can cause the processor, memory (RAM), and other hardware to overheat which may lead to a potential hardware failure. Excessive heat can also cause a significant decrease in performance as most processors automatically reduce the speed of the processor to help compensate for heat-related problems.
Your Dell computer may contain one or more fans to keep the internal components cool:
If the issue persists, go to the next step.
A simple reboot can resolve many issues almost immediately. Restarting the computer is an effective way to clear the system memory (RAM). It ensures that any errant processes and services that have started are shut down.
