"The memory could not be read" errors

I have a Dell Inspiron 9400 Laptop running XP SP2.
I keep getting an error (2-3 times per day) saying
"xxxxxx Application Error"
"The instruction at "0xXXXXXXXX" referenced memory at "0xXXXXXXXX". The memory could not be read."
For example::
"ATI video bios poller client: Ati2evxx.exe - Application Error"
"The instruction at "0x7c911639" referenced memory at "0x008b3005". The memory could not be read."
"wmplayer.exe - Application Error"
"The instruction at "0x078f0807" referenced memory at "0x08ee68c28". The memory could not be read."

Help anyone!!

It would appear, although not all error messages accurately reflect the real problem, that you may have some problems with your physical memory ie. RAM Modules.

Probably the best place to start off is to download a memory diagnostics program and run it to either prove or disprove this assumption.

I use the Microsoft Memory Diagnostics:

Running "mtinst.exe" prompts you to either:
- create a bootable floppy that will run the memory tests in its own environmeny
- extract an *.ISO file that can be loaded into most CD-Burning applications to create a bootable CD that will do the same.

Either way, press the "T" key when it runs to toggle the extended tests on, and leave it to complete all the tests.  It will keep running if left, and you can just power off when done (takes many hours).  Take a note of any errors reported.

It is usually best to test out one memory stick at a time if the system allows you to do this.
I had a similar problem with 2 Compaq laptops.  During shutdown i would get the same error.  Go to the ATI download site, http://ati.amd.com/support/driver.html, and download the latest drivers and software, this solved my problem.

I have also had a similar problem try updateing windows completely there is an issue with thier drivers that requires the DOTNET framework 2.0 or something like that. I'm not sure if DOTNET is what you need thats why I say just update windows completely doing so will be good upkeep on your computer as well as fix your problem (hopefully)

Do both critical and non critical updats to make sure you get it.

Good luck
