The thing is, when I install the driver, it works. I look in the device manager and it is listed as 7950 etc,. But, when I reboot the system to finish the installation it freezes on the splash screen.
The only thing I am wondering is that I have the PCI cable from my PSU plug into one port and the molex cable that came with the kit in the other. Does it matter which cable goes in which port (if that makes sense?) I am getting green lights on the graphics card so am presuming its right.
