Arduino Uno, Ultimate GPS, 0'96" 128x64OLED start-up issue

I noticed when I power up my GPS project, On my OLED I get a screen that looks like a snow storm. When I press the reset button on the Uno, everything starts up fine. As soon as my Pro mini comes in, I plan on soldering it all together. I don't want to have to pull it out of a tiny container to reset it each time I want to use it. Ideas......? Help!!!!

Nobody?

It could be a power problem. What are you powering it with, and how is everything connected?
