Pentium IV running Windows XP taking about 5 minutes to completely
boot. What could be causing this, and how to fix ?! ...
Take a look at the programs that are starting on boot ... I like to use
sysinternals autoruns for this.

Autoruns makes it easy to see what is starting on boot, and lets you stop
any process starting on boot. You can stop the processes which are non
essential.
In addition your memory is not exactly generous at 768 MB .. If you add 2
Gig you will notice a difference in performance, including time taken to
boot.
someone already mentioned malware .. make sure your system is clean .. scan
with Superantispyware for example.
