Youtube loading slow and videos won't start playing?

The cause of your problem is simple: your "cache"

memory & "temporary internet files" are nearly full.

This is especially true if you've been watching lots

of videos or playing a lot of games/music.

If you are experiencing either: A) slugglish loading

and buffering, B) "choppy" videos which frequently

start/stop/start/stop, C) the YouTube dotted circle

looking like it might spin for ever, or D) videos that

will sometimes come to a sudden "stop" or freeze,

that is often a sign that your cache/memory is full

and cannot take anymore.

Exit out of YouTube (but not your browser) and do

one of the steps below. Afterwards, shutdown and

reboot. Not only will this "free up" your computer's

memory, everything will be "fresh", and load faster:

DON'T FORGET TO SHUT DOWN AND REBOOT

AFTER DOING ONE OF THE ABOVE.

If you have other applications which are running at

the same time, those will slow down YouTube too.

If you have "Torrents", you might want to consider

closing or uninstalling them. A couple people who

chose me as "Best Answer" wrote that everything

worked great after they'd uninstalled their Torrents.

For some reason, simply closing them didn't work.

Also, "Adblock Plus", various Instant Messengers

and literally every "stupid video accelerator" under

the sun is known to interfere with YouTube.

Another thing you may want to consider is turning

off your anti-virus -- but only momentarily. As long

as you remain on YouTube (and do not wander off

to other websites), you will be okay, because you

cannot get a virus from YouTube.

Youtube Loading Slow

Youtube Is Slow

If a video on YouTube, Facebook, or other sites isn't working on your Chrome browser—for example, it doesn't load, stays blank, or causes Chrome to freeze or crash—try ... Turn on your computer or mobile device and try playing your video.

I had a similar problem in playing Youtube and after a lot of trial and error, I noticed that YouTube is accessing a UK server and I was actually in USA. After disconnecting Google+ where my location was UK, the speed became normal and I do not have any problem after I changed my location in Google+ and re-linked with YouTube.

What the hell is going on with YouTube

Slow stop and start won't start at all ****!!!!

My problem was particular in that I have an old Mac and have to use an old version of Safari. Here is what worked for me and I imagine it would work for anyone. I did seek a lot of answers prior to finding this. I downloaded "clicktoplugin" and "clicktoflash". That fixed everything for me. The difference has been great. I hope it works for you too.

If anything of what inukjuak90 said doesnt work, then just download the video with JDownloader for example and problem solved xD

Here I got Adblock for free http://bitly.com/1wDkpsh

It's the best software of its kind.

I hope it helps

ur space may be almost full because on some devices watching vids uses a lot of data but it may also be because of ur wifi try resting ur router
