Unplug the power cable completely to turn off and then turn back on again. Check whether there are no lose parts with missing contact.
Most probably it looks like a deeply digital problem with no do it yourself solutions - bring it to the repairman, but I even doubt he would fix it.
You can also download the Aiwa NSX-990 service manual and analyze more specifically your case. Download it from here: http://www.mediafire.com/?jc0ynzoiama or from here: http://www.4shared.com/document/rQ67hcpG/Aiwa_XG-990-NSX-990-NSX-992.html (click "Download Now", not any other button).

Assuming the memory is compatible with the system, shut the server down and open the side panel. You will be able to see other RAM modules already installed near the CPU. Add the memory by pushing the module straight down into an empty slot until it clicks and the fingers on either side close in on it. Once you're finished adding the memory, close it back up and turn it on- if you get video, the process was successful
