Sapphire R7 240 multimonitor problem
I am using a Dell Optiplex 780. I have added a R7 240 GC to the pc so that I can use multimonitor setup.
My setup are:
1x 19" monitor -VGA (1024x768p)
1x 23" monitor -DVI (1920x1080p)
However, while I can connect both monitors to the card. I get a duplicated display which is annoying. The card does not detect the second monitor. I have tried to install the driver, but halfway through installing I get a BSOD with some messages saying either it is a Plug and Play or Driver problem. I've tried the included driver CD, that failed while installing. Tried AMD's driver, that failed as well. No idea what to do next. Also, in the device manager, the PC does not recognise the GC.
I am using Win7 32-bit Enterprise version
Previous graphic was onboard. When I deleted the VGA card from device manager, I only successfully deleted the "onboard VGA" card which is the R7 (which is not detected properly by windows).
Also tried the auto detect tool by AMD, can't find the card also.
The only thing the auto detect tool can detect is this:
0x1002 0x6613 PCIE
It sees something. I am hooking the monitors to the card right now. So the card is working in a sense. However no monitor detection, and can't detect card or driver.

Any ideas what is going wrong and how to correct it?
