So I have run into this issue randomly and it can go days before being seen again. My issue is when the system goes to sleep. Sometimes it refuses to wake up and I have to flip my power switch on the PSU to off and wait for the board to discharge before it will start. This issue can happen regardless of OC'ed or not. I have already RMA'ed the CPU, swapped ram with my wife. The external and internal start buttons do not work when this issue happens. Any ideas?
