computer running extremely sluggish

[confusion]

i have a p4 1.7ghz with an asus p4t mb. i also have 768mb of samsung RDRAM and an ata100 hard drive running winxp. The computer has been extremely sluggish all the time. cpu idle always says 0% idle and in task manager, it always says that 100% of the cpu is in use. I tried doing fresh installs of xp twice and it doesnt help. also, i dont even have that many processes running in the backround.. about 5 of the services are from my user account and the others are just the system processes.

any idea?

thanks
Marc
