So, finally got the rig running perfectly. It was the motherboard giving me the issues originally. Upgraded to:
GIGABYTE GA-990FXA-UD3
AMD Sempron 145 Processor
Corsair Vengeance Blue 8 GB (2X4 GB) (since my old RAM was DDR2, heh totally forgot about that until I tried putting my old RAM in the new board. "Why won't this fit?!?! Ohhh, right.")
I ditched SMOS and BAMT for PiMP (

So, already thinking about having this GPU rig start mining the ASIC proof currencies and purchasing a few GridSeeds for the ASIC capable coins. Pretty much any profit made will be spent on more hardware for mining.
