computer genius? how do I make it inusable..

so I'm at work right but I needed to get off early in order to make my other work but this work doesn't want to let me go early.

In short, this computer is essential to me being able to do my job..if it gets..idk..a problem that cant be fixed or turns off and doesnt want to turn back on then that would very much save my day.

any thoughts? this is a dell desktop.
