Question about Dell Dimension 2400 PC Desktop
I have two dell dimension 2400's. I tried to replace the two 256 memory cards with 2 512's to upgrade the memory in each computer. They failed to boot up properly. So, I took them all back out and put back in the original 256 cards. One computer boots up correctly and the monitor can read it. The other computer boots up with all lights lighting up green correctly/no beeps on start up, but the same monitor does not read it.
If you do not see any activity and no beeps then the memory module could either be not seated right or was damaged by static. Or you could have knocked something loose (nah that never happens ;-])
To boot and generate a beep code the motherboard needs to see the first 64k of ram. So you can be sure that the problem or part of it will be the #1 memory module. So take it out and reseat it, and then try again. If nothing then swap it's position with the other module and see if that works.
Look around the case and then reseat any connectors. You may need to pull them off and then push them back on to be sure. The heat cycles from the boards running can cause them to work loose and then they just need a bump or a brush to disconnect. On some cases you can do the same just by picking it up by the corners. The case twists and pop.
If nothing is out and it still won;t work your other option is to start swapping parts into the other case to verify they are working.
