[REQUEST] G73jw 660m 2GB bios

Hey I have recently installed a GTX 660m 2GB into my ASUS G73jw but im having a lot of trouble getting any bios to work correctly. The first (660m.rom) bios I tried was from the the tech inferno forum which is modded to work in a G73jw but for a 1GB 660m but the laptops internal screen wont display anything, not even the bios, the vga port works, and overclocking is having no effect on 3Dmark results. The second (Dell.rom) is from tech power up which when flashed the laptop screen works, the vga port doesnt, an error appears when booting up (vaild MXM structure not found) and windows crashes whilst starting. I havent been able to use the laptop in months now im out of ideas of what to do? Can somone please help out im trying the best I can to get it to work but having no luck.
