Hi all!
So last night I somehow completely failed to install a replacement graphics card in my system. I'm wondering if anyone here might be able to tell me what's wrong:
I'm replacing an Asus AMD Radeon 7770 HD on an Asus H97M-E Micro ATX motherboard - with: An MSI nVidia geforce 970 GTX. I am running Windows 10 64 bit.
When I booted up the system with the new card installed, the first thing I noticed was that my temperature monitoring software wasn't detecting it at all. Sure enough, when I went to install the nVidia drivers, the installer couldn't detect the card either and refused to go any further.
I thought it was as simple as take the old one out, put the new one in, install the right drivers and off you go, but apparently not!
The one thing I did spot was that I had downloaded the 32 bit drivers instead of 64 bit - but I can't see that this would have resulted in hardware detection failure. That said, I'm not a hugely informed person when it comes to mucking about with my system - I was able to build it, but that's more or less where my knowledge ends.
My old GFX card is still working fine, I was just after an upgrade for gaming etc, and the new card is second hand, on loan from a friend until I decide I want to keep it. So it's not the end of the world if it doesn't work for me. But before I give up and stick with what I've got, I'm hoping someone can help me see that there is something simple I've missed!
Moreso, I'm concerned that when I NEED to upgrade later down the line, I'll run into the same problems. So I'd love to get some possible answers, as it's bugging me. 
Thanks,
Helios
