Given all the things you have done or changed it is Nye unto impossible to point to any one thing that could be causing your issue. The general concept is to install only the very basic things into it then add the remaining one at a time and see the progress (or lack of). However i would try removing all but one ram stick (assuming more than one is installed). If that doesn't get things running try different sticks and slots. Then go to my previous suggestion. I am wondering what caused you to do all this stuff in the 1st place and what you had done immediately prior to that IE: adding software and/or hardware? truenorth
