power issues

I have a circuit that drives 3 7-seg digits with some shift registers. I have this build on a breadboard using the pins from the launchpad and everything works fine. I then built the circuit on perfboard with a socket for the msp430. When i put the msp 430 in the ic socket and apply power i get nothing. However, if I connect the launchpad pins to the socket and power the msp430 from usb it works fine. The 7-seg and shift registers are powered from a 5v supply and I am using a mcp1700 to get 3.3v for the msp430. I see the voltage when i probe it but nothing seems to work. Any ideas on what my problem might be? Sorry I dont have a schematic to link right now.

Edit: I am using the G2553 version
