I just recently purchased an additional 1GB RAM (2 X 512MB) to add to my computer which already has two slots filled (2 X 512MB) for a total of 2GB.
I fired it up and it won't boot........all I get is the dreaded beeping on power-up.
If I run both OEM RAM cards or remove them and only run the two new Crucial cards it boots fine. But it won't boot with both the OEM and the new RAM installed.
Before I contact Newegg I would like to find out what is the problem with compatibility. I can't figure out what would be the issue as the specs seem the same to me.
Below are the specs of my system along with the old/new RAM.
Any help in diagnosing what is wrong would be greatly appreciated.............
