Using Windows XP.

Iím having a problem with my Dell Inspiron 1000 notebook not recognizing the entire RAM installed in the machine. I donít know if this problem existed from the day I got the laptop over 2 years ago or is a recent problem. The Inspiron is supposed to have 256 MB of RAM soldered to the board and mine also has 256 MB as an upgrade for a total of 512 MB according to the specifications for the service tag listed with Dell. When I looked on the Dell site for upgrades to the laptop, they recommended I get 256 MB more RAM. I bought it from Dell and tried to install it. When I opened the memory slot, I saw that there was an existing memory upgrade card in there. Here is what I have done so far, (all operations were done with the power off and battery removed, antistatic measures, etc.):
1) Remove old memory card, reconnect power, turn on machine. Boots up and System shows 224 MB memory, (256 tot minus 32 reserved). Memory from the soldered in recognized.
2) Insert new memory in expansion slot, pushed in securely, tabs engaged. Power up, System shows only 224 MB memory. New card not recognized. New Memory is Dell PC2700 - DDR333, 333MHz 200p.
3) Reinsert old memory. Not recognized.
4) Connection pins appear to look good, but so small canít be sure.
5) Circuit Cityís technician could find no problem with system, said it ran real good on 256 MB alone.
6) BIOS was upgraded to most current based on Dellís website.
7) Ran Memory Diagnostic software but turned up no errors.

Is there any way for me to test the expansion slot to make sure itís functioning? Or any other tests I can perform to get my memory working properly?

The system has to recognize that there's a slot before you'll be able to run any diagnostics on it. Have you checked your BIOS settings to make sure that there's nothing there preventing the memory from being detected?
