Some websites slow down while others are not affected.
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.
More aboutsome websites slow affected
Check for new drivers for you motherboard or network card if you have one. Good luck!
