When I have replaced from SD RAM to DDR RAM win NT is
failing to start up with error message.When I tried to
install Windows 2000 profewssional also installation
stopped with similar error message.
Whether operating system requires any update and if so
where can I find it.

Thanking You

Any windows "supports" ddr ram, the question is - does your motherboard?
Maybe you've got malfunctioning ram, or the module is improperly inserted..
?
