If it's not in your power to resolve an issue with your machine by the end of the work day, you should feel no pressure to stay late and fix it.

Even if it’s in my power to fix, why should I do this overtime?

Emergencies can happen where you need to stay an hour or two after EOD, but if it’s more than once a year I’m out, personally, local admin permissions or not.
