computer not playing youtube video?

[No regret]

....what's wrong, and what do I need to do to fix that problem?

It's playing but the video is freezing up.

Is it still happening? Sometimes, it may just be a buffering issue and then everything's fine the next day or so.

Unless its always been like this or happens with everything else such as watching a movie on the pc on a DVD or disc etc then you likely got the good old issue of buffering and connection issues with your ISP when streaming online.  The load depends not only on your ISP but the Server or site that provides your the content.

I've noticed for a long time now that YouTube has felt slower these days. On my pc, iPhones, and Android YouTube is slower.

First of all... what is your internet connection?

Not just ISP, but how your network or router capabilities and configuration will affect this also.  You should run a basic network speed test like at speedtest.net.
