I am using a zotac 6100-be with phenom II x2 245. I was able to use an old cd drive to install windows xp on this system and it is running fine, however when i try to install windows 7 or vista, after loading files it will hang for about 30 mins and return a bad driver error. ive tried to use the 6150se/ nforce 430 driver via a usb stick and it says that the driver wont work. what can i do?
