PS/2 k/b and mouse not responding on 7NJL6

Ok here's a puzzler. CT support was clueless on this one
but perhaps....

I have latest BIOS on my 7NJL6. When I power up my system,
PS/2 k/b works fine since I can press the Del key and go into
BIOS, navigate BIOS, etc. So I know the k/b works. However,
when I get to the Win2k Login, neither my k/b nor mouse
responds to key clicks or mouse clicks respectively. Now if
I reset the system by pushing the reset button, again k/b
works in BIOS, when I get to the Win2k login, k/b and mouse
WORK! So is the case on every subsequent Win2k restart.
This happens EVERY TIME after power up ONLY. Any clues?

I already have an RMA# but I want to solve it first.

USB keyboard & or mouse?
Double check the jumper on the mobo for its position.
Also make sure you've plugged in to the correct sockets. I
accidentally plugged my mouse into the keyboard socket because the
color matched.
Weirdly it worked most of the time when the usb kbd and mouse were
installed.
