You can also help some one :>)
Please revisit your post so that others on this forum will know if the solutions
were helpful or not helpful ........
You didn't say how much ram you have on board.
Ram is a real key, both the cd and the dvd are big ram hogs not to say anything about
win2k needs a bit to run.
100% is not to much if the rom is running a program but it should drop as soon as
the roms stops.
You may want to check your setting on VM on your PC windows will take control it
but you can over ride the setting to see if that helps a bit.
A quicik way to check is to read your system info and see what you have left after
windows pulls what it need to run the machine, you may have to many programs running
in the background.
TaskMrg. is also a good way to see what program is pulling the ram down other than
the rom.
Some programs will read the rom at the same time you are trying to use it like NORTON,
just trying to keep junk off your PC.
