I to am having this issue but only really noticed it lately. I tried downloading a 60+mb NVIDIA driver update today and it took well over an hour whereas before it would have been minutes.
My Firefox or Chrome (don't use IE) stalls on webpages and forget web videos when this starts to happen.
I run a home network through a router where my Vista PC stalls/lags but the other 3 XP machines (2 desktops, 1 laptop-wireless) have no probs. I know this as my sons' would be yelling while gaming if they had this 'lag'.

Let me know if this works for you.
I've followed your link Sebsworld and unfortunately it all came in good.
Anyone have any ideas as to why after 20-30 mins of online browsing Vista seems to stall/lag?
