Are you trying to install matched memory or 2 different models? It is possible that the second stick of memory OR the slot is defective. If you swap the sticks of memory, does it still work with only one stick installed?
It will work if only 1 stick is installed in the other slot(currently have the other 2GB stick in it) and it was a dual channel kit so they are exactly the same. And they work fine together cause I tried them in another PC. Its just if I try to use dual channel or stick one in the other slot only by itself it also won't post.
Yes that is what I have been trying to tell you all I already did that same thing with both sticks and different times but not both in at the same time. And whenever I stick ANY DDR2 stick by itself in the problem slot I get no POST.
