Hey guys, so I just recently installed a ASUS 7970 3GB CUII .

When the DVI is connected to the 7970, I get a black screen.

But when I put it in the onboard DVI (motherboard) it works fine.

I'm also getting the message "Fail to load ddls. Please install VGA driver." from GPU Tweak.

I have already installed drivers.

Also I get a black screen when I have two 8 pin power connectors in the 7970. But when I take one out, the comp starts normally while all fans and lights are running.

Can it be my 9 year old monitor not worthy of the 7970 ?

System.

i5 4440
8GB RAM
GIGABYTE B85M
ASUS CUII 7970 3GB
ANTEC 520W ECO

Please help me..
