It's no secret that Google Chrome is often the culprit behind a slow computer, even if your computer is relatively new.
Open enough tabs in Chrome and you can easily
eat up all your RAM, which doesn't leave much for other things you
might be doing on your computer. Extensions can use up your computer's
processor (CPU), too.
One way to check whether Chrome is to blame
for slowing down a perfectly good computer is to check your computer's
processes. On Macs, that means checking Activity Monitor. For Windows
PCs, check the Task Manager.
If you're seeing that Chrome is hogging a
bunch of your resources like RAM and CPU, you could go one step further
and check exactly which tabs, websites, and extensions are causing the
biggest slow-downs on your computer.
