ok my problem is from 20 to 30 seconds into my system boot, it sits on 100% CPU and does nothing to the naked eye, bootviz states nothing else happens during that 10 second gap. I disabled all networking, even on the firewire channel, but it still does this :s you can't use the system during this time, pulling up task manager at that time shows no activity as well. i always assumed this was to do with networking, but seems it might not be. xp2700, asus A7v8x mobo, 512mb XMs3000 ide controller card 5 maxtor hard drives and 3 cd devices.
