Pagedefrag
I installed a program called pagedefrag from Microsoft TechNet.
http://technet.microsoft.com/en-us/sysinte...s/bb897426.aspx
I use this program on my Optiplex GX520 desktop and it runs perfectly. The laptop is a different story. This program defrags the page files on reboot. On the laptop this program does not work. After the system reboots, the laptop freezes and the defrag process never starts. In order to get back to my desktop, I have to remove the battery and unplug the computer. I then have to reboot from "last good configuration". Why the difference between the desktop and the laptop? I'm stumped on this one. Thanks.

Not to be a wise guy, but have you checked with the program originator? That would be my first stop for a 3rd Party add on program.

You are not being a wise guy at all. To answer your question, I did contact the author at sysinternals.com about two week ago. Still waiting for the reply. I still feel there is something unique with a dual core processor that is different from a single core. In addition to the M90 dual core laptop, I also own a Dell Optiplex GX520 desktop and a Dell Latitude R400GT laptop. All three computers have XP Pro installed. The single core processors run flawlessly where the page file is defragmented. The dual core Dell M90 is a different story.
This is a portion of a defrag log that shows the page file has five fragments:
Fragments Bytes Clusters Name
5 3487637504 851474 C:\pagefile.sys
With my other two computers, the page files have zero fragments. In addition, the HD of the M90 is always fragmented around 40%. This high level exists even after running the XP defragmenter and a program called SmartDefrag. This has me stumped. Thanks for reading.

Problem solved:

Disk fragmentation went from 39% fragmented to 0%. Page file fragments went from five to one.

vewwwy intewesting!
fwiw~ another possible solution would be to use set the "local security policy" to delete the pagefile at shutdown:
click "start | administrative tools | local security policy | local policies | security options | Shutdown: Clear virtual memory pagefile | Properties | Enabled"
