Keyboard/Mouse issues after system build - please advise

[harddud]

Was hoping that someone, perhaps, had run into this issue before ... because I sure haven't. This is weird: I am transitioning my main desktop to a newer one. I built the new system and loaded windows and drivers using a wireless keyboard (with built-in trackball as the mouse) because I did not have another wired set available at the time. The new rig is built and RTG ... but the only keyboard/mouse that will work with it is the original wireless one. I have removed the wireless receiver from the system and plugged in a wired (generic) keyboard and separate mouse ... but no deal, the system will not recognize it.

Can anyone please advise what is going on here and how to fix? The build is done ... but I want to do some light gaming and not having a separate mouse is not allowing me to do so.

Thank you all ...

have you tried completely powering off and powering on with the new keyboard and mouse already plugged in?
