Youtube videos not loading or downloading.?

[wideachieve095]

My Youtube videos will not load or download. Yes I have deleted my history on youtube & the computer also I restarted the computer 3 times. I have an updated browser, flashplayer, and java. It still is doing the same thing. Do I need to delete the history off my network as well? Or is it my popup blocker? Could it be blocking the advertisements, keeping the videos from loading?

It could be a lot of things.

What are your computer specifications?
How old is the computer?
What web browser are you using?
What other programs do you have running?
How long has this been happening?

Your ''Cache'' (Temp Internet Files), "Virtual Memory'' and/or "PageFiling'' may be full
and cannot take anymore.  Simply delete your Cache (plus "Cookies" and "History"),
then clear your Memory with a shutdown & reboot.  Afterwards, you will freak at how
good and trouble-free YouTube will be.  Also, if you have an 'Adblock', try disabling it.

Mozilla Firefox:

Don't forget to totally shutdown+reboot afterwards.
