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.
You've completed the video playback checklist. If you're still experiencing problems, try posting a question on our help forum.
Check your browser

- 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.

Details and alternatives
Effect of clearing cache and cookies: Keep in mind that clearing your cache and cookies erases your settings for websites. Here are some examples:
- If you opted to have sites remember your username and password, they will be cleared from your browser's memory when you clear cache and cookies, and you'll have to sign in again.
- Websites might load a little slower because all of the images and content pieces have to be loaded from scratch.
Recommended first step: If you're seeing problems in how webpages are displayed in your browser, we suggest first using your browser’s incognito or private browsing mode to see if the problem you're seeing is caused by something other than cache or cookies.
If you've been redirected to this page from the sign-in box, please ignore this recommendation and follow the instructions in the section above.
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.
