Nothing shows on the screen, and it does stop at this Q code. Sometimes I think it then reboots itself and then sometimes I just hit the reset button and it comes back up. I shut the machine down and left it alone for a couple of hours and just restarted it 15 minutes ago without any issue. Just happens occasionally. I did have trouble with getting my memory stable at 2800 in the last few days, so I finally backed it down to 2666 yesterday. I wonder if I need to decrease the memory speed more.
