Need help!

When Windows XP boots-up about 2mins later the harddrive goes crazy, constantly active for about 2-5mins. Then it's fine till the next bootup.

I've had this problem before in previous clean installments of XP but sometimes I am able to stop this from happening but don't know how.

I have also got most of my startup options unchecked in the msconfig which I thought could be the problem.

Can someone help me?

Would be very appreciated.

Thanks..Brian
