Everytime i boot a a xp machine newly purchased, even though the caps lock, scroll lock, num lock keys work, any key i press to send an input to the base unit will not register. I have reboot the pc and then any key strokes are accepted.

It could be a defective keyboard or a defective motherboard.  Try another keyboard to see if that makes a difference.

So does a different keyboard give you the same results?

Can you boot into the BIOS and does it respond normally if you can?  If not, I think your motherboard is defective.

since it is newly purchased, consider taking it back & swapping it out.

exdos,

Didn't suggest that your motherboard might be defective from the start, and that if the keyboard was not the cause, the motherboard was?

Maybe the user didn't replace the mobo or the keybd, but returned the whole system & swapped it out.  Anyway I don't object if you wish to ask the mods to split 50/50.

I appreciate that, FriarTuk - no need to split; your comment is good enough.
