As I said, the hardware installation went well, and the card seems to have a good seat in its slot. However, when I installed the drivers and restarted my computer, the card does not begin to work.
I am using Windows 7 Home Premium x64 SP1, and my computer is a Dell Inspiron 580.
I had Intel Integrated graphics before, and when I tried to uninstall it, it would simply reinstall itself with Windows Update, so I used Device Manager to disable it. I followed all the hardware installation instructions to the T. After installing the latest drivers using the CATALYST installation manager, everything goes fine, but at the 'Finished' stage, under 'Actions', I am informed that "Installation complete (warnings occurred during installation). View log for details." However, when I open the log, there are no errors displayed, and the Final Status of both the AMD APP SDK Runtime and the AMD Catalyst Install Manager is 'Success'.
I use a program called Speccy to look at all of my computer's specifications, and with the card plugged in, my middle PCI-E slot, which is the one I used, says it's in use, so clearly the computer recognizes that there is something plugged in, but doesn't do anything about it.
I'm sorry if I left out some piece of information, but I've done my best to explain the problem. Could someone please help to shed some light on why my gfx card refuses to work?
