Most likley your memory is bad, not seated properly or another RAM issue.

Check your memory.

Ensure RAM is in correct slots, if applicable to your MB....(usually 4 slots, color coded, reference your manual...; drop to single stick in required slot at least until you can get a good POST)

Ensure video card is fully seated in it's slot (with power off/removed from PSU if you are going to be reseating it), and has it's PSU power inputs connected....
