I've had my Y-400 for years now and love it. Recently I started having issues and eventually discovered that the graphics card (GT 650M) has a code 43 error and is disabled. I've tried all the solutions for that (static discharge, reinstall drivers, update BIOS, etc) but haven't been able to get it to work.
So to keep my computer going, I bought a GT 750M graphics card for my ultrabay slot (it actually is for newer models of the laptop series, but I took the cover off and it seems compatible). I've got it in and I've tried downloading the drivers but I can't get it to show up in device manager. Have I skipped a step? Is there more to do? Does my first graphics card need to be functioning or can I just rely on this one? Is SLI something I need?
Any help would be appreciated.
