I'm still fighting the lock up problem that I've reported to only have in NTFS, I'm back running ntfs again, and I've done a few things to "fight the freeze". I've disabled the w32time service, as it only reports warnings in the event log after it times out, I also disabled the indexing service. For over a week the computer ran without freezing, with an uptime of 9 days +. However, during this period I never attempted to d/l any large files and high speeds, as I was always either in class or at work. Over the weekend, I've been on the comp a bit, and while downloading a large file, a freeze hits me (when I woke up this morning, comp had froze at 200KB/sec). I've attached a shot of the conflicts in my system, I know xp has the irq sharing (or does it?), but I'm not really sure where to start on troubleshooting this, could the NIC be to blame?
