Avgtdix.sys BSOD

I have about a 6 year old desktop dell dimension 4700

I have had an annoying problem with BSOD
which gave a message blaming AVGTDIX.SYS

I did lots of research trying to figure it out, and now
for me at least, I seem to have a rather unexpected solution

I tried all the obvious fixes... virus and malware scans
chkdsk in case it was a disk problem
I tried re-installing avg virus
I tried finding the seemingly corrupt file....
all got me nowhere

finally I decided to give up on AVG, and replace it with another virus SW
And the first thing that happened was another BSOD
but this time not mentioning avgtdix.sys
so it seemed to me that AVG was not the problem

I thought that was very strange
then I remembered that a couple of years ago I replaced
the mother board --- some unknown issue caused it to be unreliable


In the process of doing the transplant
I noticed lots and lots of dust in the machine.

and it occurred to me that maybe the motherboard problem
was related to all the dust
although since I put in a new motherboard, the dust issue was only
speculation in the end

Anyway, to finish the story I took out the memory chips on my machine
and cleaned the contact strips

My first effort was wiping across the contacts lengthwise
the machine would not boot up after that effort.
scared me good

then I took out the memory again
and this time wiped the contacts pulling
parallel to the contacts and off the chip
I could feel gunk coming off in my finger tips

And, after that, my machine has worked fine with no BSOD

........

I am no expert or anything
but just wanted to share the story for what ever value it may have.
