As a massively popular web browser, when Google Chrome has an issue, it’s disruptive to a lot of people.

And perhaps the only issue more frustrating than slow speeds is when Google Chrome outright won’t open.

Fortunately, this issue is often easily solved.

There are several things you can try. 

Here are four of the most common remedies if Chrome won’t open, with instructions for Mac and PC.

Check to see if Chrome is already running on your computer

On your Mac, select “Force Quit.” 

Chrome might unbeknownst to you be running — hidden — in the background of your computer. Check to see if Chrome is open, and force the browser to quit, if so.

For Mac:

1. Press “command” + “option” + “esc” on your keyboard.

2. A window will appear called “Force Quit Applications.” Look for Google Chrome. 

3. If Chrome is there, select it and then click “Force Quit.

For PC: 

1. Press “Ctrl” + “Alt” + “Del” on your keyboard.

2. Select the “Task Manager​.”

3. Under “Processes,” check if “Google Chrome” or “chrome.exe” is present, and if so, click it and then click “End process.”

Delete unknown applications

Move the app to your trash. 

A lot can happen when you’re not looking at your computer that will slow down web browsing — even when you think you’ve been vigilant about keeping unwanted programs from being downloaded. 

So, here’s how to delete unknown or unneeded applications.

For Mac:

1. Open your “Finder” from your Dock and select “Applications” from the left hand menu.

2. Check for any programs that are unfamiliar to you.

3. Right-click on any unfamiliar programs and select “Move to Trash.”

4. Empty your trash by right-clicking on the trash can icon in your Dock and selecting “Empty Trash.”

For PC:

1. Open Chrome.

2. Click the three vertical dots in the top-right corner and then select “Settings.”

3. Select “Advanced” from the left hand menu.

4. Under “Reset and clean up,” select “Clean up computer.”

5. Click “Find.”

6. If prompted whether or not to remove unwanted software, tap “Remove.”

Reboot your computer

Restart your computer. 

Ah, the classic “Have you tried turning it off and on again?”

But the truth is, if a program or process that’s running on your computer is causing the problem with Chrome, rebooting your computer might be a quick and dirty fix.

Uninstall and reinstall Chrome

Empty your trash and get rid of Chrome. 

If none of the above has worked, your best bet is to uninstall and reinstall Chrome. 

Uninstalling and reinstalling Chrome can fix a myriad of problems, including ones with your search engine, Flash, pop-ups, updates, or others that can prevent Chrome from opening.
