I have a Dell dimensions 9100 with 1gb ram (2 512mb sims) I added 2 1gb sims and the system would not power up. I removed the memory and still won't power up. If I remove the battery from the mother board, umplug the CPU, wait a bit, re-install the battery and then power cord it automatically powers up. BUT, there is no power light on the power button. The system will reboot, go into setup but once I turn the power off it is dead till I remove the battery and power cord again. Any ideas would be most helpful. Oh,it seems to run fine when it is up but running Dell diagnostics crashes and dumps - gal la blue screen.(be it full, mother boad diags whatever I tried so far)
Possibly a bad power supply. If you remove all the memory and it still won't power up unless you remove and re-insert CMOS battery that is a symptom of a defective power supply

RAM can be finicky so first test all memory slots with a known good stick (your 512MB). Make sure you're starting from a complete power down and you get a POST beep (hopefully your system is set up to beep when it powers on) and everything loads up all the way through to your OS.
Once you do that with all your memory slots test with the new stick by itself in all memory slots. If neither of the memory slots work with the new stick but you verify that it works in another system you should then check your BIOS settings and RAM timings to ensure compatibility with your stick. If you can't find the timing on the RAM stick itself, look up the manufacturer's part number for the information.
Good luck!

I hope that you checked and those 1G units are compatible with the slots...I mean if the pc supports 1G units...some mo Bo do not support more than 512 on a ddr slot...if the compatibility is OK ...try to see if inserting one unit in the slot where the 512 it id now ...make it work ...this will verify the compatibility too...if is working it means that they should work together too
so ...removing the bios battery was a smart move ..cause it needs to get t default optimal settings ...but ,,,cause we are talking about ddr 1...you should look for a setting that allow multiple slots too ...and also check the units compatibility to work in multiple units way...
after all that is done ...even if the pc do not sees the ram memory entirely ...I suggest to reinstall the operation system from scratch ...I do had a problem like this with an assus pc ...and after reinstalling it was ok ...

from what you describe, they system will not shutdown. So try the following:

I found the problem. The cable to the power switch came a little lose when I added the ram. The cable plugs into the motherboard right where the memory sockets are. I was checking all cables, connections, chips etc and found it.
