I cleaned off all the drivers and installed Omega's nVidia and it's now running at a stable 35-40 range in normal environments, low 30's at the intense. The problem is pretty much fixed, although I still have a question about my RAM showing up at PC2100.
It seems like a bad request for help, because I'll probably have no one sure-fire answer, but I'll post my problem anyway.
Recently, I went to go move around some cables in my case to help with cooling, and afterwards my computer did not boot up what-so-ever. I ended up completely rewiring...
