I am in a dilemma and need  help.  I have a Dell Dimension 8400.  Here are my 
 specks::
 
Processor-----------------------Intel (R) 4  CPU 3.00GHz
Memory-(RAM)-----------------256  MB
Operating-System---------------Microsoft  Windows XP Home Edition
Operating System  Version------5.1.2600
 
I was trying to format  cause I had gotten that blue screen, but it would 
never go all the way through..  When it was copying the files.. it stopped midway 
and I did this three  times.  I finally called a tech here to come see what 
was wrong.   After fooling with it for 2 hours, he pulled a memory stick out 
and the  formatting was able to go on through.  He said I needed another memory  
stick since that one was bad which he said he would order for me.  He never  
did, and here I sit with a slowed down computer, but at least it  works.
 
I got online with a Dell  tech who sent me the above instructions on how to 
install the required memory  sticks.  (The Tech here said he would order me 2 
GB of memory - 1 GB each  to replace two that were in there.)but I have not 
heard from him  since.
 
Now, in reading those  instructions Dell sent me, it says this in there 
(which confused me so that I  don't know what to do now mainly cause I am not 
familiar with the innerds of a  computer)
 
 
<<< If you  install mixed pairs of DDR2 400-MHz (PC2-3200) and DDR2 533-MHz 
(PC2-4200)  memory, the modules function at the slowest speed installed.  
Similarly, if  you install memory modules with mixed CAS Latency (CL) rates, the 
modules  function at the speed and CAS latency capablilties of the slowest  DIMM.
 
Be sure to install a  single memory module in DIMM connector 1, the connector 
closest to the  processor, before you install modules in the other  
connectors.
 
NOTICE:  Do not  install ECC memory modules. >>>
 
Since the tech never came  back to the house to fix my problem, I'm having to 
do it myself.  I need to  know what I am to do and exactly where those memory 
sticks are and which one or  ones I am to remove when I install the two new 
1GB ones when I buy  them.
 
Now.. I had gotten back  with a second Dell tech and asked him what to do, 
but he was as puzzled about  this as I was.  Therefore I got no information from 
him in this  regard.  I just dont know if I am to take all four of those 
memory sticks  that are in there (or does this computer only have 2 in it) or just 
take 1 out  and replace it with the 2 news ones I will be getting..  but the 
1 and 3  seem to be in one slot and the 2 and 4 in another.  I am totally  
confused.  Thanks for your help.  Harriet
