Boot up in Safe Mode.

As mentioned, some software malfunctions can be caused due to OS settings or other system problems. Windows and Mac operating systems both feature a troubleshooting environment known as Safe Mode, which disables applications and processes that are not crucial to the system, theoretically making it easier to isolate problems.
Most Windows computers allow you to enter Safe Mode by pressing the F8 key as your computer is booting up. If you're using a Mac, you can enter Safe Mode by pressing the Shift key while or directly after your computer boots up. Once your computer is in Safe Mode, launch the problematic software application and attempt to replicate the problem you encountered while your computer was in normal mode. If you don't encounter the same problem, there's a good chance that the issue is being caused by your OS or another program rather than the application you are troubleshooting.
