My system: Dell Inspiron 530, XP Pro, 2G Ram.  Recently I've started getting this MOM.EXE error message about 6 to 7 times a day. The instruction number is always the same, but referenced memory number varies. This error has something to do with my video card which is an ATI Radeon HD 2400 PRO but I don't know what.  

the mom.exe file is located in 2 places on my computer:

C:\Program Files\ATI Technologies\ATI.ACE\Branding\MOM.exe
and
C:\Program Files\ATI Technologies\ATI.ACE\Core-Static\MOM.exe

[See attached graphic]

Uninstall the catalyst control center and driver and reinstall the latest driver and catalyst control center from ATI.

SteveH--mom.exe is probably not malware.  What is it?
http://www.file.net/process/mom.exe.html
So that fits what you report about ATI.
Perhaps get the latest Catalyst Control Center --CCC.
But back to possible malware  http://www.overclock.net/other-software/372119-mom-exe.html
You say this started recently.  Can you think of any new hard/soft ware you installed about that time.
Perhaps try a System Restore.

Since location of fault is same - your RAM chips are faulty.
mom.exe is component of ATI Catalyst, reinstall cannot fix broke RAM.

run memtest86 and remove bad chips
gheist - are you looking at the same SS i am?  I see the same fault in two different locations in the memory.  I'd say it's a bit fast to rush to RAM error ?

I ran memtest86.. it ran for about 50 minutes and says "Pass complete, no errors".

OK - ruled out hardware issue - reinstall latest catalyst (with help of catalyst modder from driverheaven if necessary)

gheist, I already uninstalled the catalyst control center and driver and reinstalled the latest driver and catalyst control center from ATI.  [see above response to jamietoner]
Steve,
I know it may go back to the basics, but have you tried:
1. Removing and re-seating the video card.
2. Booting into safe mode, uninstall all video drivers.  Reboot back into safe mode, install video card drivers.
I'm poking in the dark here i know.  Just tossing my 2c in though.

FlooringPro: tried that, no change.

points increase.
Could be a problem with the card itself, or some other program running that has a compatibility issue with the ati drivers. Do you have another ati card(or know one you can borrow) to test with? Also you may want to try a few older driver versions.

I would recommmend full driver uninstall from safe mode and complete clean reinstall with ATI latest driver - it helps with vista (like removing 10 old driver releases befor installing)
Steve,
Here's an interesting article i found.  Not sure if this helps or not:
Aw, MOM--Error in systems running ATI Catalyst
We've seen an unusual error popping up on occassion in relation to ATI's Catalyst driver suite, version 7.2. It happens universally in both XP and Vista environments.

The error points to a problem with MOM.exe--an executable that has the same unfortunate name as a virulent piece of malware. (If you get a MOM.exe error and you don't have the ATI catalyst installed, then you've likely got the malware.)

ATI is aware of the problem and the engineers are looking at implementing a resolution. For the time being, ATI advises customers who receive this error message uninstall Catalyst version 7.2 and put version 7.1 on the system instead.

I would recommend catalyst 9.5 from game.amd.com just in case.
since it mentions malware - do full av update and system scan IN SAFE MODE WITH NETWORKING.

FlooringPro, I think that must be an old article. AMD has a 'Previous Drivers page' with 18 versions from v8.451 through v.8.62, but nothing as far back as v7.2.   I've uninstalled and reinstalled from Safe mode, run the AV scan (no problems), and now I have the latest Catalyst/driver version on it v.8.632, but I still get the same error message when booting, and cannot launch the Catalyst Control Center. I get the "Could not load file or assembly MOM..." error shown above.

looks like broke .net

so - uninstall catalyst control center and drivers.
make use of "autoruns.exe" from sysinternals to remove their trails
Rmove driver tweaks in safe mode: http://downloads.guru3d.com/Driver-Cleaner-Professional-download-745.html
INSTALL DRIVER FROM Windows Update - it does not need .NET (v8.533.1.0)

you can install ati southbridge and amd processor if it is relevant for your motherboard.
(VGA mode at this moment)
So far you got without .NET, no need to go further.

Uninstall all the .net (assuming no other apps use it):
http://blogs.msdn.com/astebner/archive/2006/05/30/611355.aspx

Install .NET 1.1 only if you need it AND .NET 3.5 SP1 (which has latest patched 2.0 included)
Follow with all applicable Windows updates.
reboot and install full http://game.amd.com/us-en/drivers_catalyst.aspx Catalyst 9.7 (or locate older version 9.3.1 for your card from www.amd.com)

Keep in maind that Catalyst versions and file versions are not same. Catalyst v7 contained file v8.x but vile 7.x was for Radeon 7000 series.

You have to mod catalyst using mobility modder.net before installing on dell computer.
Otherwise CIM does not install and you have not changed driver at all by catalyst installation so MOM.EXE is same for all of time.
Steve,
Unfortunetly, im not a wiz with ATI cards.  I wish i could take you further but i'm at a loss as well.  From a troubleshooting standpoint, personally, i would begin to look at swapping the vid card with another ATI and see if i could get drivers/CCC to load.  It may be something hardware related.

Inspiron 530 has Intel mainboard, for that you need some ATI hotfixes for drivers.
Yes - MOM.EXE crashes with memory configurations of cards that was unavailable at cards making - like 200M with 1GB shared mem (not in BIOS, but in MobilityModder)
That is why i am suggesting complete cleanup.

If there is really ATI card in your system it is HD radeon and driver 9.7 from game.amd.com is best to date.
If you never paid attention to 3d tweak then windows update offers stable and seamless driver updates.
