Looks like maybe heat was not the issue. Perhaps the mainboard is toast. During RAM testing with single sticks in combination with differing single slots I discovered that my RAM appears to be good, but for some unknown reason the board is trying to run DDR3 on the second slot at just 200MHz. The machine passes both sticks in the first slot and also does not exhibit any issues with just one stick of RAM in the first slot. Fun times =(

I was able to bandaid it while I wait to get a new board by underclocking the RAM substantially.

Today my random eBay shunt box arrived. I spotted this one on eBay and bought it straight away. $15. I stripped it during lunch at work and kept only the voltage and current meters and some switches. Pretty good salvage for $15, considering a 300V volt meter and 30A current meter with it's shunt is probavly worth over $50.
