Perhaps you've blown a cap or mosfet on the motherboard it's self or you have you have water somewhere causing a short.
Maybe try unplugging the PSU power from the board and taking out the battery for 10-20 minutes to let all the power out of the caps and mosfets, before bootup clear CMOS and try to boot....
If that doesn't work try taking the ram out and heating the slots, could be too much jelly in the ram slots and/or pci-e slot...
Have you tried each stick of ram one @ a time?
5.7GHz for 06 is awesome


great F-ing job Q!!!
Also I thought I read somewhere 06 degrades the 980x not 100% on that but you said the CPU still works....
