These are my specs:
GPU : XFX Radeon HD 7970
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3242918

Monitors:
Acer S232HL and VISON V1721DB

and
http://www.newegg.com/Product/Product.aspx?Item=N82E16824161024

my monitor goes black(disconnected) when connect my second monitor.
Acer connected with HDMI and Visio with DVI connector.

I tried to do it with single monitor first, they works fine. But as soon as I plug in the second monitor, I got black screen and I have to hard reset my computer.

Could someone help me with this problem please.....

Is it possible I got a bad GPU?
 
actually i thing thats the psu problem looks like your card is 500w minimum requirements very electricity hungry card.may help set lower resolution for both monitors saved and try again.

I don't think the problem is PSU.
I unplugged my hd and 2 fans, I still got the same problem.
I tried to reinstall my windows 7.
It was fine until I installed my driver for GPU, so I guess the problem is with GPU's driver or software?

What do you think?

I forgot to mention, my computer was fine with those specs until I installed water cooling system this morning.
 
is the water cooling using any power from the same spu.
