In my opinion Windows got nothing to do with these problems. You did not mention about your Browser. (also read Additional at the bottom)

First of all do as follows:

1. Un install Adobe flash player

2. Un install Java

3. Clear Internet Browser's History & Cookies.

4. If you use any kind of Download Manager disable it from startup menu.

5. Try to use Firefox browser with following add on:

Download Helper (for download)

AddBlock Plus (to stop adds)

Now re-install Adobe flash Player and Java from their website. When the Adobe flash player will be install successfully you must watch a short flash movie.

Install Firefox with add-ons I have talked above.

Re-start computer, go to youtube try your luck. Hope this should work fine. In case you notice nothing has changed then un-install Firefox and add-ons if you wish.

Additional:

When you use Youtube please do not run any other software,e-mail or messenger.

Also check: Processor is more than 2 GHz, RAM is more than 4 GB and Hard drive got enough empty space. To run computer faster processor should be fast with best Video graphic card. RAM plays a vital role. More memory is always best.

Conclusion: Not only internet speed/software but also High speed Computer processor, A good video graphic card, Enough RAM (memory) and large Hard drive is essential.

Hope above information will help you.

I think you need a new system. How old is yours?
