This problem is most likely due to the way that XP is handling the power saving features
of your computer.
There are two types of power management: ACPI and APM. APM utilizes power states
that are somewhat limited, e.g. during standby only the monitor and HD are shut down,
but CPU fans, etc keep running. ACPI, however, utilizes more effective power states,
using either the S3 state (suspend to RAM) or the S4 state (suspend to disk, or "hibernate").
It appears that previously you were able to use ACPI, and now only APM is functioning
on your system. Hence, you still hear the fans running. You may need to upgrade
the drivers for your motherboard's chipset so that XP can work properly with your
system, or make adjustments to your BIOS. However, I would first consult Dell for
more info; changing BIOS settings can be devastating if you aren't familiar with
what those settings mean.
Look at this link for more info on APM and ACPI.

Good luck to you.
