Help with gpu please

[PCpartQuestions]

This is my GPU http://www.newegg.com/Product/Product.aspx?Item=N82E16814125476

My MoBo http://www.amazon.com/gp/product/B005PX3UYA/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B005PX3UYA&linkCode=as2&tag=c09_11-20

Are these compatable? Because the computer worked fine with my Radeon 7750. But when the 270x is installed the monitors display nothing. The fans come on but nothing else. Also, the mouse and keyboard dont work with the 270x. Please help

I plugged both 6pin wires into the GPU. The gpu fans spin but in displays nothing.

are you able to put your old card back in to see if that still works? if you can, maybe shove that in and get the latest drivers before swapping cards.

optionally, does your motherboard have onboard graphics? maybe boot only with that, and uninstall any and all traces of other GPUs before rebooting with the new one in place.
