A software problem may be affecting your computer. Access the Windows Task Manager to observe what programs or applications are using your CPU. Try to minimize or negate the tasks that routinely use a large portion of the CPU. Additionally, Windows startup tasks can be delayed or disabled using Task Manager (prior to Windows 8), or Startup (Windows 8, 8.1, & 10).
