extremely slow reboot

I use a dell laptop with windows xp and am having extremely slow reboots.

specs:

MS Windows XP Home SP3

Intel CPU T2060 @ 1.60 GHz

2.0GB RAM

ATI Mobility Radeon X1400

Dell Inspiron 9400

Using Windows task manager I click on shutdown then restart

Once it restarts the first thing I notice on the screen is

Dell

then Windows XP

then a full black screen

Welcome on a blue screen appears at 1 minute 45 seconds

It takes more than 3 minutes for the day of the week, time and date to appear in the right lower corner

It takes more than 5 minutes for the start button to become responsive to a click

It takes more then 7 minutes to open Mozilla Firefox

How do I troubleshoot and get a faster reboot?

Using msconfig  services, hide all microsoft services the only item are my lexmark printer and Microsoft Automated troubleshooting service

under the startup tab the only item to start with reboot is ctfmon

With most software off on reboot how come it is taking so long?  Also I use Mcafee antivirus plus and I had the Mcafee boxes unchecked with reboot.  That is no evident active antivirus system load with reboot

i have checked for malware using Malwarebytes full scan approximately 8 hours and no malware

I have checked for malware also using Kapersky free download and it too found no malware

I use Ccleaner, Privacy Mantra and Glary utilities regularly
