E-Machine T3120. I have replaced all the hardware installed in this machine. New memory was also bought and installed. Also replaced the power supply and cd rom...nothing straightened this out. It stops at the post where it says "verifying DMI pool". I tried to re-install winxp home and it stopped during setup and said there was not enough memory in the machine. It has of course 512 mb ddr, but I replaced it just in case it went bad, no dice. Went into bios and it only show s like 64k, and it is not highlighted so I can get in to look at it better. From all I can gather, the memory is not registering correctly. Is the slot Bad? Is it the cpu? Is it the motherboard? Been working on this for almost 3 days. Thanks in advance for any help. By the way, it was working perfectly for 2 years, then 3 days ago I turned it on and here I am.
