The five minute fixes that solve 90 percent of tech problems

[DistantSequence]

After years of being the family IT department, I have concluded that most tech support is five moves repeated forever. Restart it, check the cable, check for updates, clear the cache, and try a different browser or account. It feels almost insulting to suggest them, and yet

The trick is doing them in order and actually doing them, not saying you did. The number of times restart it has fixed something after the person swore they already restarted is beyond counting. Sleep mode is not a restart, and yes I will die on this hill

So what belongs on the list that I have missed? Give me your universal fixes, the boring ones that work, so we can pin the ultimate lazy troubleshooting checklist
