If you have 120Hz but not 144Hz, then it's not a DVI cable problem or a DVI wrong-port problem (that often limits you to 60Hz)
To re-add 144Hz, you can use nVidia Custom Resolution (add 144Hz "Reduced", not "Auto"), ToastyX Custom Resolution Utility (likewise), or ToastyX Strobelight (add "120Hz Strobed", "121Hz" and "144Hz" in strobelight-setup)
