Hello everyone recently I had purchased an iBUYPOWER gaming rig which has a corei7 processor, 2GB Ram, 750w psu. It has an inbuilt HD5770 graphics card installed in it along with two extra pci x 16 slots, so in all there are three slots. When I removed the HD5770 card and installed an DUAL Fire GL V5600 workstation card along with the drivers, it ran normally without any problem. However when I inserted the second graphics card, it did not display any thing on the screen. I reinstalled it again and again but nothing was happening. Can any one help me to figure out my problem.
