Installing Additional Ram

[DESRTRATTE]

I INSTALLED MORE RAM CARDS, BUT DON'T KNOW HOW TO HELP MY PC RECOGNIZE THE ADDED HARDWARE. I'VE RUN THE "ADD NEW HARDWARE WIZARD" AND IT DOESN'T SEEM ABLE TO FIND THE NEW CARDS. THEY WERE INSTALLED CORRECTLY, SO I'M STUMPED. DELL DIMENSION 4100, 32GB HD, 1GB RAM, 733MHZ, PENTIUM II, PC 133. (YEP, I'M A NEW PC OWNER.)
