Computer freezes on youtube

My Windows 7 PC (64bit) has Firefox browser. When I go to youtube ... for simple video links after playing a few it freezes. So strange I cannoit invoke task manager (cont+alt+del). The PC freezes completely. I get no option but to hard power off and let it reboot.
This happens frequently and almost 3-4 times a day. I googled and reinstalled the Adobe flash player..but it is not fixed.
I get the same problem if I use chrome browser instead of Firefox.
Anyone could suggest how to troubleshoot?
Thank you.

Uninstall current version of flash player and install debugger versions

You should get an error dialog next time

Freeze issues usually refer to memory issues.  If you have more than one stick of memory, remove one and try it.  If the issue persists, either more that stick to the other slot, or swap out the sticks.  If you only have one stick, swap slots.  Worst case scenario with memory is you get a different stick and test it.

If memory is not the issue, run CHKDSK /R /X and see if that fixes the issue.  

Does this happen in IE or any other browser?  Try that.  If it only happens in Firefox, uninstall and reinstall it.

Have you tried uninstalling and reinstalling the Google Chrome or Firefox? As asked above, does this happen with the IE? Try installing the IE9 and see if that helps.

If not, then I would suggest to boot the machine in safe mode with networking and see if you are able to browse to any site in which you can watch videos or online movies.

I also wouldn't mind trying this..

https://browsercheck.qualys.com  --->> Scan your browser thoroughly and please fix the scanned the issues

As this hung up your machine and you have to hard reboot it. I also would not mind in upgrading the BIOS and the firmware version, if it shows OLD.

If it's a homePC, I also would not mind trying any graphic intensive game, see if that hung the whole box. Check the graphic driver version too.

Good Luck..!!

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

Thank you all.
I have installed the flash player debugger versions and will see what happens next time it hangs.
Also went to https://browsercheck.qualys.com  and fixed all that scan suggested.

I have never opened the RAM slot myself -- but will certainly try that next if other tries fail.
I have the same problem with IE9..I tested that before.
In safe mode the graphics are not clear...so not sure if that I would like to do ... but will check.

Thanks a lot.

I know only VGA mode is installed by default in Safe Mode with Networking. My main motto was to confirm if the machine hung up on your when watching any videos or not. This could be the GDI issue too on the server. Instead confirming with each and every service by stopping those services one by one and test run the browser will be much of a time consuming task.

Sure, check your results and please get back.

Good Luck..!!

Just a hunch, but worth a try: open any flash video and immediately pause it.  Right click on the movie, select "Settings", and disable hardware acceleration.  Doing that has helped me with similar issues.

laptop or desktop?  

if desktop, is there a separate video card?  if so, and if you have a spare card, could you swap it out?  or do you have on-board video so you could pull out the video card completely?  I'd like to eliminate the card and the drivers altogether if possible.
and regarding video drivers--are they up-to-date?  BIOS too?

freezing is very often a memory issue.  not sure how hardware-savvy you are, but i would definitely suggest moving and/or swapping memory.  i'm sensing since you said you've never opened the "memory slot", you mean the cover on a laptop.  do this if you can.  if you only have one slot (not one under the keyboard, perhaps) then your best bet would be to pull it out and re-seat it.  also, run MemTest if all else fails today--let it run overnight.

anything peculiar in the Event Viewer?

let us know...

Try disabling FLASH hardware acceleration.

When running any FLASH video, pause it, right-click on the picture, and choose "Settings...".

On the "Display" tab, make sure the "Enable Hardware Acceleration" box is unchecked.

Click Close to save settings.

Exit the browser.

Thanks a lot.

I have run into a bigger problem since then. I uninstalled some program -- the laptop does not boot.
I will try as you mentioned right after I get it to boot.

Thank you.

Thank you all. I have fixed the bigger problem.

Now I have disabled the "Enable Hardware Acceleration" as you said above.

Ok but actually the problem is not limited to youtube or other online video .. the same freezing happens when running a local video file locally....

It is a HP Pavilion dv6700 laptop....
I will swap the memory card the next time it freezes.
Thank you.

Oh!  A DV6700!  Why didn't you say so earlier?  You likely have the nVidia problem.  See this recommended service:

Disabling the "Enable Hardware Acceleration" actually fixed the issue substantially. It freezes much less often now and I am more than ok with it.
Many thanks to you all.

That's good.  You should install coretemp (or equivalent) and watch the temperature closely to avoid burning out your video chip.  If you feel the need, there was also a BIOS update for this model to try to fix the overheating problem by running the fan more.
