What exactly are the dimms? you said 2 were 128mb and one unidentified.
Try removing all but one, and make sure that one is in the first slot 
and try powering up to see if it is the dimm, or the slot.  then try 2 
matched in slots 1 and 2.  Then swap dimms and try the various 
combinations of dimms and slots to see if any other one or combination 
will work.

Sometimes you must use the slots in the order they are numbered.  If it 
is an older pentium it may need a matched pair of dimms in order to even 
work. (for example I had one that required 2 32mb dimms (or simms??) 
paired in slots 1 and 2 in order to see 64mb of memory.  Using one 16mb 
and one 32mb did NOT work)


What is the actual MOBO and CPU?  it appears to be ATX, but that can be 
pentium, pII, PIII, or something else.  
If you know the make and model of the MOBO you often can go to the 
manufacturers web site and get specs, settings, and even manuals for the 
board.

What about bios settings?  have you tried the defaults in case some 
weird setting is causing the problem?

May not be a bad connection.  Memory issues can be very deceptive.
