While I agree with Matt that the fluctuation ranges are not alarming (though not ideal) I do notice the 12V path is low even at it's high point. Important supply voltage there. I'd try a replacement.. can't guarantee a fix, but a new PSU can't hurt on a machine more than a few years old. If you tried re-installing already ...
