Hi all, I've got an iMac DV SE which never causes any trouble - as long as it stays disconnected from the internet. But a certain time after I plug in a network cable (I've tried Ethernet and Internet Sharing via FireWire), the machine starts to freeze from time to time, forcing me to interrupt power supply. The freezes occur always while the browser (OmniWeb, TenFourFox, Safari, RSSOwl and Classilla) is loading a web page. This is what I've tried: I have -reset PRAM, reinstalled Tiger etc. -run Apple Hardware Test which doesn't reveal any problems -run TechTool Pro 4 several times which doesn't reveal any problems -run memtest for hours without problems -stressed the CPU using SystemLoad (to determine cooling issues), without problems. Does anyone have an idea why the hangs occur only while being connected to the web?
