What should you try first when an application locks up in a computer?

I woulduse ctrl+shift_escape to start the task manager. While C+A+D does determine if its alocked app, to get out of it you have to then hit escape. You still haven't fixed the issue. Yes you can start the task man or reboot. But, if you use C+S+E then you have started the task manger and have determined if the computer is locked. But now, if not locked, you are at a screen where you can look at CPU ram utilization as well as end a hung task.

In my opinion more useful
