Hey guys.

I've been having problems with youtube videos either making my PC freeze or turn off. I've tried it in the latest Chrome (HTML5) and Firefox (flash).

I've just bought a new GPU - R9 280x (latest drivers)  and the problem persists. I had a GTX260 before.

I can't work out what it could be!

I've tried different browsers, plugins and graphics cards! Oh and I've run memtest with no errors.

Any ideas would be greatly appreciated.

win 8.1

Edit - I've watched things locally and using Plex over a network with no issue Did you do a Google search?  This has been a problem for many this past year.
The most relevant might be this posting on Tom's HARDWARE.

Computer freezes during Youtube
The post vectors into many related issues. They say turn off video acceleration. Try another browser.

Also, not documented, overclocking the CPU can cause this.




Sorry for the long gap there.

I have tried turning off acceleration in Flash but it MADE no difference.

Also note that  Youtube HTML5 now instead of Flash for a lot of it's videos.

My CPU is running at stock.

I'm still having this issue..... Any other idea?Well, there are a lot of people saying what  you say. They have problems that look like hardware issues, but only on you tube. Note that You Tube requires Flash and there are some issues with Flash.  And you need also the latest version of Java.

Other kinds of video players do not need Flash and Java, so you will not see it on other things which  use other media readers.
This look like the definitive collection of  people who complain about it.

Issues with Flash? Problems with Adobe Flash or YouTube Videos?

It is a long, long thread. HOPE it helps. 




I suggest you download and install CCleaner and run its Cleaner utility.  Once installed, you will see the Cleaner button at the top of  the left column when you open CCleaner.  The default settings are fine for most users.  No guarantee this will HELP but no harm in trying and it might, indeed, resolve your problem.

The regular version of CCleaner does come bundled with a toolbar.  You can unselect it during installation of CCleaner.  Alternatively, you can get the Slim version, which does not have the toolbar bundled with it; otherwise, it is the same as the regular version.  If you start with the Slim version and you want to stick with it when updating CCleaner to the latest version, you need to observe which version (standard or Slim) you're downloading when you update; otherwise, you might end up with the standard version when you intended the Slim version.  You can either download CCleaner from the links I have embedded here or directly from the maker, which is http://www.piriform.com/ccleanerOk, I've run CCleaner, done a clean install of Flash and tested Youtube on Firefox with the Flash plugin with the problem persisting.

So I can rule out:

Browser
Graphics Card
GPU Driver
Flash version (tested 14 and 15beta)
Flash hardware acceleration

I'm GOING to try downgrading to a Flash player from 9 months ago...
