I installed windows 2000 pro. on my pc. I upgraded the memory but
still it runs real slugish, you click on a program either on the desk
top or a file name under my documents and it takes sometime about 1
min. to come up. Somtimes it want even open up.

Dear aaguila,
     I am no computer expert, but I recently had the same problem.  As
it turned out there were several things running in the background that
were messing me up.  I had downloaded a file that needed realplayer
and it was slowing things down.  Also, my temp file was full with
about 350 files.  After uninstalling realplayer and emptying my temp
file, it made all the difference.Good luck

read about system service that run in the background, see if some of
info. here helps you 'tweak' your system, by shutting off some stuff:

You may be having harddrive issues. Double check that your harddrive
is configured properly in BIOS (system setup screen), usually by
pressing F2 or F10. Enable Bus Mastering or 32-bit access if the
options are there. Your manual will help with this.

If your harddrive is working really hard (HDD light is always on even
when running simple programs like NotePad) it **may** be not up to the
task of running Windows 2000. Check to see if your system
specifications are in line with what Microsoft recommends.

I have an old IBM that would operate like your machine, it was simply
not up to spec. (AMD 333 Mhz, 128 MB RAM, 6 GB HDD)

Could you please explain if this is a new computer which had no
operating system or if you installed Windows 2000 over another OS?  If
so, which?

How much memory did you have before the upgrade and how much do you
have now?  Keep in mind that Windows 2000 has more stricter RAM
requirements than Windows 98.  The minimum RAM for a Windows 98
machine would be 32 MB of RAM.  For Windows 2000, the minimum should
be 64 MB, although 128MB or more definately helps.
