Computer slow? Three things to try

Most slowdowns have a simple cause. Start here.

Most slowdowns come from a few common causes. Work through these in order.

1. Restart properly

  • Windows: select Start > Power > Restart. Use Restart rather than Shut down: shutting down doesn't always fully clear things out.
  • Mac: select the Apple menu > Restart.

Restarting also finishes installing updates, which keep your computer secure and running smoothly. If your computer asks to restart for an update, try to do it that day.

2. Close apps and tabs you're not using

Each open app and browser tab uses memory. Save your work and close anything you don't need right now.

3. Check your storage

  • Windows: go to Settings > System > Storage to see what's using space.
  • Mac: go to System Settings > General > Storage.

To free up space, clear your Downloads folder, empty the Recycle Bin or Trash, and keep work files in OneDrive or SharePoint rather than on your desktop.

What not to do. Please don't uninstall software, change system settings or run “speed-up” tools from the internet. Some are scams, and changing settings can stop things working. We'll take care of anything beyond the steps above.

Still slow? Contact us at support@deepnet.com or 707-755-8000. Tell us when it's slow (all the time, or only in certain apps), what you were doing, and whether anything changed recently. If your computer is several years old, we can also look at whether it's due for replacement.
