Keyboard troubles

[Alwaysredy]

The power supply in my pc died and I just recently replaced it. When I start up the computer; its says "keyboard error or no keyboard detected." I've tried several different keyboards using every port available but nothing. Any ideas?

motherboard might have crapped out as well.

try cheapest solution first: find a known working keyboard. (edit: the ones you found work?)

If it works, your keyboard was fried
If it doesn't.. congrats, your mobo is extra-crispy.
