Hi Kajetan,
You may try cleaning the air vents of the computer. Below are the steps to clean the air vents:
- Check the vents on the computer to see if they are covered with dust and not allowing heat and air to pass through
- Turn off the System
- Unplug the AC Adapter
- Remove the Battery
- Use Compressed Air to blow the dust out of the vents
You may also refer to article Here.
Note: Please use compressed air can. When using compressed air can, use the can according to the directions on the side of the can as it may cause damage to the computer if used incorrectly.
I would also suggest you to scan your computer for virus/malware using a good antivirus program.
The issue might also occur if the CPU usage is high all the time. You may follow the steps below to identify the process/application consuming the CPU resources :
- Press Ctrl+Alt+Delete on keyboard
- Click on Task Manager
- Click on Processes
- Click on CPU to arrange the tab in ascending or descending order
Please share the process consuming CPU resources so that we can isolate the application that is causing issues.
You may also try running the computer in safe mode and see if the issue persists. For starting the computer in safe mode you may refer to the article Here.
Please reply with the findings. Will take it further.
