My initial gun response was the ram or an overclock.
The only thing I haven't seen mentioned is what bios you're on. This could all easily be answered by it being an older version of the bios that isn't as stable
I re-flashed the bios with most recent, this bios was working for a week before this issue started, though could be the cause as I dont think it was unplugged after I initially updated until now.
