Crystals usually don't come in a DIP package.  Could it be that you have
a crystal oscillator instead?  If so, then hook up its output to the OSC1
pin (the pin number depends on the PIC package), and leave OSC2 open.

If you are using a crystal, then you didn't mention the caps to ground.
I usually hang a couple of 22pF caps from each pin of the crystal to
ground.  Of course, if the crystal is series resonant, then another setup
is required.

Look at pages 33 & 34 of the PIC16C5X datasheet to make sure that you
have a good clock.
