I just installed W2K Pro (pristine install) and now the machine is almost unusably slow. As I write this, I'm about five letters ahead of what I see, and I'm not *that* fast of a typist. I try to play a fullscreen mpeg at 1600x1200 and I get about 1 frame/sec.

Anyway, the machine wasn't like this when it was running NT4, so its either W2K's fault or poor drivers.

Heres the machine:
2x pII 400
Iwill DBS100 (i44BX, Adaptec 7895)
Adaptec 2930CU
Elsa Gladiac (nvidia geforce 2)
intel eepro100
creative live value

Now, my first thought was crappy display drivers. Unreal Tournament will bench at about 40fps, but will play like its running about 3fps.

Then I noticed that moving files around on disk, copying to/from my network would make explorer use 100% of one cpu for the duration of the copy, and the copy would take way too long, too. Its almost as if I had IDE disks using pio, not UW SCSI disks.

There are precious few optimizations that I found poking through the control panel. I'm sure there are many more in the registry. Has anybody seen this problem before? Any ideas on what the culprit might be, or at least some direction I can go toward finding whats going wrong?

r u running any programs when using windows 2000? use ctrl+alt+del and click on task manager and have a fiddle with that program. i think there is a lot of programs running at the same time and using up ur processor.

if u r running any utilites that try to improve ur computer's speed, forget it as windows runs better by itself.

Try ye olde take-everything-out-one-by-one and-see-what-happens trick. Uninstalling stuff in device manager as you go.

My latest build is slow and I've just noticed that I've got cards using bonkers IRQ's (31, 36, 40 & 128) and I'm wondering how the hell that happened. This could be my problem and I'm going to see if I can get eveything within the standard 15 (without sharing) to see if it helps.

Check your IRQ's too: is your embedded controller sharing resources with the add-in card ? Dissociate them and see if it helps. And, FFS, was dual channel U/W not enough for you (!).
