Definitely try another keyboard as others have suggested.
And another USB port ... maybe even try a PS2 keyboard if the mobo has one
and you have one of those keyboards handy.
On the topic of power...
It's possible that your power supply is failing. You'll experience
sluggishness ... it might take a few minutes to shutdown or reboot where it
should only take a few seconds. Or when it gets worse, the machine refuses
to turn on.
If you can run a rescue OS on the system and it still acts up, then its
most likely a hardware problem.
