"It was fine yesterday."

I hear this all the time. No warning, no gradual slowdown — just suddenly, everything feels a little off.

Here's the thing most people don't realize: computers don't change for no reason. Something always changes. It's just not always obvious what.

Usually it's a background update, an app that quietly started using more memory, or something that installed alongside something else.

I wrote a quick guide to walk you through what to check first — nothing complicated, just enough to point you in the right direction.
