Have been noticing this problem over the past month, basically my internet browser (either IE7 or Firefox) seem to lose connection with the internet, if im downloading any torrents or stuff through my newsgroup they carry on downloading from the internet, and i do not get disconnected from msn messenger but i cannot send any messages i get 'message delivery failed'. It always appears to happen around the same time, anytime between 6-7pm. I have to restart the PC to fix the problem, im using windows vista 64. Any suggestions what the problem maybe
