If just the HIS card is in the comp works fine, so I know its the VisionTek card.
let me save you some trouble. I have-
-made sure both 6-pins are plugged in
-made sure the card is firmly connected into the top pcix16
-temps on this card never went over 70c
-tried both dvi ports and was recieving video, just black
msi 770-g45 mobo
ocz 550w psu

Sounds to me like your card bit the dust. You might try resetting your BIOS on your mobo. It's a long shot, but I've seen stranger things happen....
