I did a new test board today and it shorts

[Nick]

here is the deal, I setup a test board that I have been working with for a few months, but I shipped it off to the head engineer. So I started making another test board and it just shorts out when I give it power.

Please tell me what retarded mistake I'm making.

My connections are

pin 1 +5 (reset)
pin 8 +5
pin 9 clock
pin 10 clock
pin 20 vdd ground
pin 19 +5

These are the basic connections that I have hooked up and I have short.

I pulled up the datasheet to verify, but i'm stupped it must be some dumb thing I'm missing.

When I turn on the power supply it goes to from 5 to 0 volts. I used this power supply with my previous test board with no problems. I eve swapped out wireless board to see if that would fix the problem.

thanks,
Nick

And the PIC would be????????

Any other connections or just the PIC?
Is the PIC in a socket? If so, what happens if you remove the chip? Does it still short out?

[Nick]

i forgot some important information,

the pics is a 16f876 and it does not short if i remove the chip.

That one is easy.

Vdd = Power
Vss = Ground
