strange problem with new gtx 650 ti

ok i have recently buy a asus gtx 650TI-O-1GD5, what i think maybe is DOA,
i have video but when i install driver y get error 43, cannot initialize hardware, i have tested different drivers, and two different PC, the strange is, I run GPU-Z and get 2990 of vmemory so maybe the problem is corrupt bios?, i have 2 days google it, the app what asus use to update or reflash bios see my bios but thats says my bios is current to date but dont have option to reflash, so i have tried to flash with nvflash and with a bios of here with the closes model to mine but cannot because is not compatible with my card so maybe someone have or can upload a bios of my same model?

thanks in advance, hope someone can help.

my system specs:
i7 4820k
MB asus rog rampage formula iv
PSU coolmax bronze 1000w

Remove all drivers, maybe you' had an amd card in there, it may conflict.

Download latest Nvidia driver, install. Select Clean install. (you seem to have a old forceware driver. )
