-Clear CMOS either with a MB jumper or by removing the battery.
-Make sure the video card and memory are securely inserted(Sometimes they require a hard push to seat properly).
-Try the memory in different slots.
-Place the MB on a piece of cardboard. If you get a display, check for a ground between the MB and the case or the standoffs.
-Swap out components or have them tested.
