VGA cooling nightmare...plz help

i spent all day/night trying to figure things out and made me realized maybe its not suppose to work? I dunno i have an Asus HD7770 1G5-rev2 mod it with Artic acce s1 plus cooling kit but instead i added a 4pin fan(enermax120mm) mod it and mounted it to the VGA 4pin fan connector. Now it messed up my graphic driver and i cant use the softwre that came with it ( Asus Tweak ). I keep getting "Fail to load dlls. Please install VGA driver". I uninstalled/installed 100x times used 3durusweeper etc. still same problem and to make matter worst i re-installed windows 7 and still the same.

Does anyone know whats going on? Now im back to using my iGPU i dont even know if i can use the HD7770 or if i broke it?? i thought its just a driver issue but it seems like its more. Too tired to think....

Hope i get some feed back when i wake up. I would really appreciate it
