Cpu Almost 100% Usage From Start

Hi:

My PC configuration:
Windows XP; P4 3.0; 1G RAM; 40G+40G*2(RAID 0);

discription:
The CPU have almost 100% usage from start, so the sound of startup is shaking. Any program will cost high usage of CPU, so the system run very slowly.

I have run Norton 7.0 for Antivirus but nothing found, the same as running FIX it 6.0, and defragment anyway.

the logfile is post below:
