I have a weird problem. Since buying a new computer, my internet has been acting strangely. Every few mins, some sites I go to suddenly slow down to crawl and won't load, while other sites and downloads for example are not affected by the problem. And after 5 mins or so, it goes back to normal (just to slow down after a while again).
I am pretty sure the problem is with my PC, because the other internet user in the house (we share our connection) has no problems and it started happening once I switched to using new PC.
I also upgraded from Windows XP to 7, if that has anything to do with it.
