    Is this RAM that came with the system or did you add/swap it out? If BIOS isn't detecting it all I say either something wrong with the RAM or it's not compatible with your system for use.

    Considering the age of the machine, I would start with the basics first.

    With the power off, reseat your ram to make sure they have a good connection.

    Run memtest86 as one way to check for faulty ram.

    If you really have 4GB of COMPATABLE RAM, a BIOS reset may fix it. With the PC powered off, open the case and remove the CR2032 CMOS backup battery for AT LEAST 10 minutes. Reinstall the battery, observing correct polarity. Power back on and check the total memory in the BIOS.

    Is the 4GB of ram in one ram card, or in two 2GB cards?
