Troubleshoot playing videos on your computer
You may experience poor video quality — slow loading, buffering or choppy playback — due to a number of factors, such as issues with your Internet Service Provider (ISP), the number of connected users or devices, your hardware, your software and software configuration, your connection to the internet (wireless or ethernet cable), whether you have exceeded your allotted data quota, or problems with the video itself.
While the Video Quality Report provides information on how your ISP typically performs, this checklist includes troubleshooting tips to help fix playback issues.
Some of these steps require updating your browser or restarting your computer, so you may want to open this page on another computer or device so you can easily use it as a reference.
Check your browser
Check whether the video is working after trying each of these internet browser (e.g. Google Chrome, Firefox, Internet Explorer, or Safari) troubleshooting tips:
Refresh your browser window. On many browsers, you can press the F5 key or Command+R keys on your keyboard to reload the current page.
Close all other tabs and windows in your browser.
If you’d like the best YouTube viewing experience, always upgrade to the most recent version of your browser.
Find out if your browser is updated
Go to whatbrowser.org and you’ll see what browser you are currently using.
If you see “This is the most current version,” your browser is already updated!
If you see “There is a newer version,” click the Update your browser button and download the newest version of your browser.
Update Adobe Flash player
Some videos on YouTube are streamed through Adobe Flash Player, a plug-in for your web browser. Having the latest version of Adobe Flash Player ensures the best viewing experience.
Here’s how to upgrade to the latest version:
Check your Flash Player version
Download the latest version
Exit your browser once you’ve downloaded the file
Open the Adobe Flash Player Installer on your computer to complete the installation process
If you have any issues during the installation process, visit Adobe’s help page.
Click the toolbar icon Chrome menu.
Click Show advanced settings.
In the Privacy section, click the Content Settings button.
Click the OK button to close the window.
Refresh your browser to update the settings.
Microsoft Internet Explorer
If you’re not already there, launch the ‘Browser’ app on your device
Press your device’s < Menu > button
Exit and reload the site you were trying to access in Browser
On your device’s home screen, tap Settings
Exit and reload the site you were trying to access in Safari
Clear cache and cookies
Cookies, which are files created by websites you’ve visited, and your browser’s cache, which helps pages load faster, make it easier for you to browse the web.
Clearing your browser’s cache and cookies means that website settings (like usernames and passwords) will be deleted and some sites might appear to be a little slower because all of the images have to be loaded again.
How to clear cache and cookies
Tip: If web pages aren’t displaying correctly, you can try using your browser’s incognito or “private browsing” mode to see if the problem is caused by something other than cache or cookies.
Restart your home network
Here’s how to restart your home network:
Turn off your computer
Unplug your modem and your wireless router if it’s a separate device
Wait for about one minute
Plug in your modem and wait until no new indicator lights are blinking on. If you unplugged your router, plug it back in and wait until no new indicator lights are blinking on.
Turn on your computer and try playing your video
Connect your computer to your modem
Try plugging your computer directly into your modem or router with an ethernet cable, rather than connecting wirelessly. If this fixes the problem, reposition your modem or router, as interference or range issues may have caused the poor connectivity.
If you’re connected directly to your modem and still can’t play your video, you may want to check with your equipment provider to make sure your modem and Internet service are working properly.
Check your internet connectivity
If the above steps didn’t help, try these tips to improve your internet connectivity:
Make sure your internet usage isn’t at capacity — for example, someone on your home network is downloading a large file while you’re trying to watch YouTube.
Check your computer for viruses, spyware or a hard drive that’s reached its full capacity.
Move your router to a new location to improve signal strength. Your router should be elevated off the floor (like on a bookshelf or desk), and placed in a central location in your home.
Move any cordless phones, microwave ovens, or other wireless devices away from your router. These devices often cause wireless interference.
