GTX 770 2GB DirectCU II issue, monitor goes blank

Got a new GPU, my monitor goes blank when I try to play a game.
I have the driver up to date

I have a Corsair CX750M PSU, it has 62 A on the +12v rail.

Could my BIOS be the issue ?Should I update it? I dont know how to do it. I have tried a patch from the ASUS bios update but it says 'This patch does not support this card'

Specs:
CPU: Intel® Core™2 Quad Processor Q9400 at 2.66 GHz
GPU: GTX 770 2GB DirectCU II
Memory RAM: 6GB
Windows 7 64bit

You should try also to ask/browse at the Asus ROG GeForce Graphic Cards Forums must be some having kind of this issue you're mentioning.

You're PSU is fine for One GTX 770 DC2 card. Try not use the adapter Asus have furnished inbox but power it directly from the PSU dedicated viudeo PCI-e rails.

Be careful with updading your Graphics card vBios. You could save the original one using latest GPU-Z (small icon in Bios version section).

I saw that the last vBios for that card GTX 770 DC2 is from October 30, 2013, which seems if yours is brand new that it got the most up-to-date vBios.
