You can't fix the "+12 rail thing" you look on your power supplies and you gotta make sure your +12v rail has enough power on it. Chances are if you look on your powersupply and it says +12v - 15a then your PSU is your problem. My +12v rail has a max of 22a which is enough for my needs. I already calculated I could have 15 fans running, my two hard drives, cd- burner, dvd-rom running and any graphics card and still be able have enough power. The Ultra 500w Modular connection PSU has a 34a +12v line so that would be damn near impossible to use up all that.
