I have a 128mb pc100 ram in my computer running on Win2000. I'm trying to upgrade the ram but each time my system does not start up.

If I try to add more ram the ram, the BIOS appears to load up correctly and Window starts loading but then I geta blue screen telling me the ACPI is not updated. What does that havea to do with memory?

If I try to take out my old memory and just use the new one, the BIOS will not even load.

I've tried this with several different memory chips, the lastone being Kingston. All the chips are compliant with my motherboard.

I notice that my memory chip is smaller. Its 128 pin, but in terms of the chip size, they are smaller. Could that have anything to do with it? Also, when the memory check inthe beginning starts, it tells me I have NVRAM.

NVRAM (Non volatile Memory) holds its content without power. ROMs, PROMs, EPROMs and flash memory are examples. So sounds like your memory chip is bad and the computer is trying to boot with only the BIOS NVRAM. You may have fried your RAM chips with ESD(Electro Static Discharge). Before touching any electronic component you should first discharge the static buildup in your body by touching an unpainted part of your computer case.
We can eliminate bad RAM by starting in safe mode.
Reboot and hit f8, choose start in safe mode.
Does the computer start? If so go to Start>settings>Control Panel>Power options and select Never in all of the fields.
Reboot. Did that help?
ACPI handles (amongst other things) the Suspend to disk file on older laptops which allows the contents of memory to be dumped to a file on your hard drive, shuts down the computer and on reboot reloads the information to memory.
This should not stop your computer from booting. However Power management is notorious for causing lockup and freezes.

Let me know if this works or not.
Note: Start in safe mode to eliminate the question of bad RAM chips as the source of your problem. If it starts your Memory modules are fine. My first post was unclear.
