I noticed that it runs fine with 72Hz and testing 75Hz works as well. But after applying it, sometimes when I restart my computer my secondary monitor will complain that resolution is not supported. It works fine for 72 Hz though. I have played with several different timings and same thing. Once at 75Hz the the second monitor will complain. Is there anyway to fix this?

Are these monitors connected with DVI? If turning the monitor off and back on resolves the problem, then you might be hitting the edge of what the monitor will accept, so it only works some of the time, but then the question is why is the other monitor not affected? If you swap the monitors, does it affect the same monitor or does it only affect a specific port on the video card?
