I'll second Scott's recommendation of ZoneAlarm. But I'll add that you should never, ever try to remove it or it'll royally mess up your TCP stack.
I'm highly suspicious that the disk activity stopped when you unplugged the modem. There is a worm going around that let's people host porn sites on unsuspecting people. It's possible you have such a worm in your computer. And though ZoneAlarm will keep that program from reaching the internet it sounds to me that the worm is what's crashing your machine and it will continue to do so until you remove it with Norton Antivirus or similar GOOD virus killer. You might also try Spybot Search and Destroy.
