1- Use compressed air can to blow accumulated dust out of your vents.
2- Use msconfig Start tab and uncheck all except Microsoft and your antivirus program, OK and restart.
3- Run Malwarebytes to check for an infection that may have got past your antivirus program.
4- Uninstall any program you do not need/use at all.
5- Recheck CPU usage in Task Manager.
6- Check temperatures in Speedfan or similar program.

You have to be a little bit crazy to keep you from going insane.
