Explorer.exe Application error. . .The instruction at "0x01b63c26" referenced memory at "0x01bc6260". The memory could not be "read".

The RAM chips are brand new.  I've tried different user accounts.  I'm going to attempt to start it in safe mode to see if it still gives the error.  The error will pop up within seconds of closing out the last one and just hoses the computer out.  You can do nothing with it.

Another thing to check: Which version of Internet Explorer do you have installed?

"You may receive a "The memory could not be read" error message when you click certain Web site links in Internet Explorer 6":

It might be as well some problem with Internet Explorer toolbars, such as google, yahoo, etc. which may be corrupt. If you have any of those installed, try reinstalling them, or uninstalling them:

Uninstall any toolbar that may be installed in your browser:
Go to control panel > add/remove programs > Uninstall all toolbars found there...

Also, From the Task Manager>File>New>explorer.exe

Does the Desktop/Taskbar all display properly? If not, might have an Image Hijack.

Back to the registry under the following key.....

HKEY_LOCAL_MACHINE\XP\Microsoft\Windows NT\CurrentVersion\Image File Execution Options

Look for a subkey named Explorer.exe. If it exists, kill it......

From the Task Manager>File>New>Regedit.exe

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

Look for the following values....

Shell=Explorer.exe
Userinit=C:\Windows\system32\userinit.exe, <~~~~ Should look EXACTLY like this, including the comma...

Last but not least, try replacing your c:\windows\explorer.exe, with a known good copy, either extracted from the CD/i386 directory, or c:\windows\system32\dllcache. The good file should be around 1008KB if I am not mistaken, and should be signed by Microsoft. .....

John, when I run explorer.exe from the task manager, it does display as normal, but the error pops back up almost immediately.  I will try the regedit and look for those values that you suggested.

How to configure Windows XP to start in a "clean boot" state
http://support.microsoft.com/kb/310353

Start by disabling all startup items, and retesting. If it works ok, enable half of them, and retest. If it works again, enable another half, and so on and so on etc.....

If no startup items removed help the problem, try unchecking all NON MS services under the services tab.

That seemed to work to a point.  The error still popped up at startup, but it did not make the computer lock up.  I tried several programs with success and no error.  However, when I logged out and logged back in as another user or logged back in as myself, I was still having the error and it was locking up the computer.
I tried doing the msconfig again and restarting, with no success now.
