Generic: off the shelf no name brand from Wal Mart.
I know the difference between a ps/2 and a usb. My HP keyboard that come w/ the machine is ps/2. It doesnt' work right now, it is source of all this dialogue. The wal-mart keyboard is also a ps/2. It didn't ork either...yes, I rebooted trying both and separate times, with the computer off. I went and bought an adapter ps/2 to usb from radio shack, and tried it too, following the same minute and correct processes detailed above.
As for the device manager, I have uninstalled and reinstalled about 5 times now. I bought PC Tools Registry Mechanic, because it said it fixes this code 41 problem...it don't! The error code says, "windows has loaded the device drivers, but cannot locate device. Under hardware, it say that the keyboard is plugged into the port.
