Question about Dell Dimension 2400 PC Desktop
I have a 256 mb memory card and I am adding 512 mb. When I put it in it beeps like 5 times and then boots up, but my monitor stays in sleep mode and my keyboard & mouse don't come on. What should I check?
The supported Memory types for Dimension 2400 Series is PC2100 (266-MHz) or PC2700 (333-MHz) DDR SDRAM (non-ECC). Supported Memory capacities are 128, 256, or 512MB and a Max if 1GB (1024MB).
The first obvious question is does the new 512MB Memory module meet the above specification? Some Memory modules are able to steep down speed.
If it does, then first ensure the new memory module is properly installed. Take ESD (ElectroStatic Discharge) precautions or you may damage the new memory module and/or the system board.
To proceed compare the system beeps and diagnostics lights color and sequence to the Advanced Troubleshooting guide.
It is possible that the new memory is DOA (Dead On Arrival). Or there is a new fault on the system. If you have access to another compatible system, you may test the new and old memory modules. You may also swap the new and old memory modules to determine if the memory slot is at fault.
Lastly, if you remove the new memory module, does the system complete POST (Power On Self Test)?. If it does you may indeed have a DOA or incompatible part.

Sounds like the stick is not pushed in far enough top make full contact .Make sure the locks have droped in all the way to the card you are installing

several beeps in a system is caused by a memory issue -- If you've recently added or tried to add additional memory to the computer and have started getting these beeps. Remove all new memory you've added to the computer. If the computer works fine after removing the new memory you're encountering either an incompatibility or defective new memory.
Sometimes when the computer is moved and/or over time a memory stick can become loose causing the computer to be unable to read the memory or get errors as it's reading it. Try fixing this issue by opening the computer removing each of the memory sticks you have in the computer and then placing them back into the computer.
If reseating the memory did not resolve the issue try swapping the location of the memory. If you have only one stick of memory in the computer try moving it to another slot and then boot the computer.
If you have more than one stick of memory try removing all but one stick of memory and boot the computer. If this does not resolve the issue try removing that stick of memory and try one of the other sticks of memory.
the specs can be found at this link
the system you have is upgradable to 4G of RAM, and this RAM must be installed in equal pairs
so if you have 4 slots to insert memory in (assuming you will retain the 2 256M) , you must install the other slots by 2 512M, 2 1G or 2 2G DIMMs -- make sure you isntall exact same DIMMs, dont mix memory makers or specs, other than what Dell specifies
memory type must be
PC2700 (333-MHz) or PC3200 (400-MHz) DDR SDRAM
i hope this helps --
