Please don't type in all CAPS, as it is considered shouting when
comunicating via text, and difficult to read. As to the computer
problem, two things. One, changing the operating without knowing the
cause of the "crash" only adds to the confusion as to why the computer
doesn't work. And two, Windows 2000 is a NT operating system as opposed
to the DOS based Windows 9x series and require a completely different
set of hardware drivers. You will need to research all your hardware
including the motherboard and make sure you have the correct Windows
2000 drivers installed. Visit the manufacturers web site for each piece
of hardware that you need replacement drivers for.
