Have you checked that you really have +5 at PIC's pins?

The 78L05 is oriented in the boar correctly and there is only 5V powering the PIC. The thing that's getting me the most is that this is a intermittent problem and I'm running out of things to look at beside the floating inputs. Can these 4 pins just be pulled high or do then have to go to ground?
