What’s Slowing Down Your Computer
Did you know? A cache is similar to a junk drawer in your kitchen- you may have it organized at first, but it can get messy and overflowing over time. In addition, if you leave your cache filled with gigabytes of old browsing data and temporary files, it can turn your computer into a sluggish device.
The thing is, your cache is not there to make your computer act sluggish- it’s actually made to help your computer run faster by storing bits of information from websites and apps you frequently use. It’s there to take note of important stuff that might be helpful for a quick reference later. But once it is full of outdated information, then, it starts to cause problems- yup, you’re computer turns into a digital sloth. By clearing your cached images and files, you’re ensuring that you are accessing the most current form and content and that the web pages you visit function correctly.

Google Chrome Cache Clearing: Your Browser’s Express Cleanup
I’ll let you in on a little secret – about 80% of the “my computer is acting weird” calls I get are from Google Chrome users who’ve never cleared their cache. After thousands of house calls, I’ve got this process down to a science, and here’s my exact method that works every single time:
How to Clear Google Chrome Browser’s Cache and Website Data
- Click the three dots (menu bar) in the top right corner of your Google Chrome.
- Select Settings from the drop-down menu.
- Click “Privacy and Security” in the left sidebar.
- Select “Clear browsing data”.
- Select your time range from the dropdown (pro tip: choose “All time” for a fresh start).
- Check the box for “Cached images and files”.
- Click the “Clear data” or “Delete Data” button.
Pro tip: While you’re there, you might want to check “Cookies and other site data” too, but remember clearing your browser’s cache will sign you out of most websites. And while you’re there, you can also clear recent history of your browser. Just click the Menu> History Menu> Click Clear Data/ Clear History.

Mozilla Firefox: The Hidden Refresh Button

- Click the menu button (three horizontal lines) in the top right corner.
- Select Settings from the drop-down menu.
- Click Privacy & Security in the left sidebar.
- Scroll down to Cookies and Site Data.
- Select “Clear Data”.
