My p8z68-v pro/gen3 won't provide any video display at all. The memory LED lights up and there is no posting sound. When I remove all memory it does post with the code for "no memory". The ASUS site says I need to manually adjust the memory timings and voltage "for a test". Memory is 16 gb of Kingston HyperX ddr1600. CanI do this with no video? How do I do it? No other component lights are on. Thanks, Ted
