Linux hard freeze (diagnosis?)
Ok...this will take a little while to describe, so bear with me.
The computer in question is a P4 running Slackware 10.0. When running graphically, it runs KDE 3.2. Running audio & video editing software, or games of any graphical complexity do not cause problems. However, when running either Mozilla 1.7.3 or Gaim (I forget which version, but it's recent) the computer will randomly hard freeze (ie. keyboard and mouse lockup) and I can only reboot by flipping the main power switch off and on again in the back of the machine. I've been doing anything from sending an IM message, to downloading software, to loading a webpage. The freezing only seems to happen when I'm using somebody's bandwidth.
The motherboard and graphics card have worked reliably with little problems. My father has had to switch the cable modem once (it's his network) because the one we had before would hang up randomly. (Ironically, the one we have now is no better, or at least it seems that way when I'm online.) Given the problematic history of the cable modem, I'm inclined to think the problem lies somewhere in the networking, but I'm not quite sure.
I have another, older machine running Slack 10 as well, but it doesn't run any kind of graphical interface, and I've had no problems with that one when doing any sort of network communication.
Anyone got any suggestions as to where I should look?
