No hardware changes at all and out of the blue Windows is only recognizing 8g of my 16g of RAM. When I run CPU-Z it shows 16g. I checked each stick individually and they are all healthy. Anyone have suggestions?

Also, post patch 5.0.4 running 10x WoW is maxing out my CPU something fierce. In game I changed it from DX11 to DX9 and that helped a little but not anywhere near where it was 3 months ago when I took a hiatus. Is there some miracle I missed after one of the earlier patches?

Thanks in advance!
