No keyboard or mouse when booting into win 2000

I recently moved my two hard drives into a new system and ran a system repair. When it boots, the mouse and the keyboard are not working. Both are ps2 type but I have also tried a USB mouse to no avail. Things work fine in the bios screens and when I boot the recovery console. They go away after the system boots into windows.

I installed a new instance of Win 2000 on the other hard drive and it boots fine and the mouse and the keyboard work. I have checked for the presence of the mouse drivers and they are there. I have checked to see if there are additional filters in the registry for these devices, and there aren't. I have tried exporting the keys for the keyboard and mouse from the good system and imprting them into the registry for the system that won't work, and that did not help either.

Any ideas?
