Explorer.exe Crashes - The memory could not be written - Update! Still Need Help!

>From my research the following problem is experienced by a vast number of
people and the only common denominator is the use of WinXP SP1 and possibly
a number of patches however, I have utilized system restore to the point of
ten days before I noticed the problem begin.

At random times when trying to open a folder (directory), I receive the
following popup: "Application Error: The instruction at "0x77f57ec4"
referenced memory at "0x00000067". The memory could not be "written". A
similar popup appears reading: "Application Error: The exception unknown
software exception (0xc015000f) occurred in the application at location

When going to the event properties in the Administrative Tools, I see under
application events that the following notation appears: "The shell stopped
unexpectedly and explorer.exe was restarted." It is a winlogon event with
event number 1002.

When this error occurs I have to click as many as three popup notices.
Following that, all icons on the desktop disappear for a few seconds, the
screen is refreshed, icons re-appear and most applications running in the
background (anti-virus, etc) do not appear in the toolbar until logging off
and back on.

I am suspecting one major area that I haven't tried -- Changing out memory.
Six weeks before I started having this issue I upgraded to ABIT KD-7 RAID
m/b with Athlon XP2700+ CPU; 2048 mb DDR PC2700 ECC non buffered RAM. Would
adding an extra wait from the cycle between memory and CPU help? I.e using
Registered ECC RAM? Before I go to the added EXPENSE of getting registered
RAM I would like to have confirmation.

Other things I have done to try to correct the issue:
1) Running sfc/scannow to restore original .dll's, etc.
2) Re-installed SP1 (to restore possible corrupt explorer.exe file)
3) Flashed BIOS
4) Dropped down to 1024 mb and checked each memory module;
5) Tried various RAM settings withn the BIOS; and enabled Shadowing and
6) Gone back to several system restore points (even before the last four
critical updates from Microsoft);
7) Uninstalled the various pieces of software that I added since the time
this issue started to occur;
8) Tested RAM with both MEMtest86 and Windows Memory Diagnostic;
9) SiSoft Sandra 2003 indicates no warnings or applicable suggestions for
changes or modifications;
10) Swapped out CPU's (one Athlon XP-2700+ with another of the same specs);
11) Checked the system board temperature (averaging 35 to 38 degrees C) and
CPU (averaging between 36 and 39 degrees C)

Only one hardware update since this issue started and that is going from a
2mb cache harddrive to an 8 -- same disc size, RPM, ATA-133, etc. Old drive
was imaged over to the new.
For those techies needing a rundown of programs running when the crash
occurs let's just say it varies, but here is a list of those running at
start up:

If you notice something is this missive that may sound an alarm to you, then
please let me know. I have published this to various help groups like
Extreme Tech, Annoyances.org, WinXPNews.com, Computing.net and Hardware
Analysis.com (also the Abit and AMD support grounps too)! Others are having
this or a similair issue and I would like to get all our heads together in
nip this thing once and for all!
