Can't Install Memory

Question

Please some one that knows what you are doing I need your help. I have a Dell Latitude CPx J that I'm trying to give a memory upgrade. It currently has only 128MB of RAM, now I have two 256's that I want to put in but it doesn't work when I do. If I leave the 128 in the first slot and put a 256 in the 2nd slot the laptop will start to boot up and it will say the size of my memory has changed but just before it opens windows it will say (Windows could not start because file C:\System32\drivers\pci.sys is corrupt or missing). But of course I tried to put in the two 256's together first but the PC want even come on. Can anyone help me with this? I'm desperate. Oh, by the way I definetly have the right part. Thanks

Have you tried one of the 256 modules alone in the first slot?  If that works, I'd look at a bad second slot.  If not, either you have the wrong memory or it's defective.   Dave

Unless the memory you bought is PC100 Low Density 16chip modules, you do not have the right parts for your CPxJ. High density or PC133 modules will cause the same result. There are many dealers who sell what they call PC100/PC133 RAM that is high density and will cause many Dells set up for just PC100 to puke.

I bought the part from dell and it is the one they said I needed for my model but maybe they sent me the wrong thing.

Crucial shows this module will work - they test:   http://www.crucial.com/store/mpartspecs.asp?mtbpoid=A982FA30A5CA7304   It looks like an 8 chip module so I would call and ask specific questions first.  Your CPx J should take 512mb max.
