Re: My 639 credit score in May 2000. It dropped like a rock by February 2001 to 574. Thes reasons as I outlined in some prior posts are: Too much new credit awarded to me. I ran up a 2,900 bill on Capital One to show my limit. Too many inquiries. I am on the credit wagon now. I will pay Capital One off this week. I am letting the credit age. I have never been late or missed a payment on any account since 1998.
