Look for a BIOS update - if the mobo maker took the time to implement memory readdressing in later BIOS versions, you might recover your full 4 Gb. Otherwise, you can write them off.

What bit version of Windows are you running?
What RAM modules specifically are you installing?

You're probably using a 32-bit operating system which limits the usable ram to around 3GB of RAM.
Your Intel E5200 does support 64-bit architecture, what you can do is install a 64-bit operating system to utilize 4GB of RAM or more.

It does sound like a 32 bit win OS.
