Got my 980 AMP Extreme Edition. An Issue

[Gamer000]

Hi, I got my 980 AMP Extreme yesterday and I connected it. I connected using the 6 pin + 2 pin = 8 pin. I connected using 2x 8 pin connectors. I did that correct right ?
But today morning, when I started the PC by using the power button on the case, there was no display . I had to hold down the power button to make the pc off and then press the power button to turn it on again and this time I got the display. Everything went smooth.
My query is why there was no display at the first time and I used the right connectors right ?
Btw, I have Cooler Master 700 G PSU.

Any help would be great.

Thanks in advance.

Bios changing for the new card?

What card were you using before?

Also maybe try to fresh install the drivers again. Don't use the ones in the cd go to nvidia.com and get the latest ones.
