I downloaded the drivers off of AMD and it said the components are already installed (express) but when that didn't work i tried the custom instalation and that said no hardware(or software for AMD) detected. BIOS is tricky for me, I am merely an amateur, and the PCI options were confusing to me but had two versions (current?, or legacy, and UEFI) but didn't say anything about it being populated or not. Power light for the GPU comes on. I have plugged it in during any of the changes I have made (have been using integrated mobo graphics in the meanwhile).
Any advice would be appreciated I gave as much information as i could barring anything i may have forgotten during this long troubleshooting process and I will gladly answer any questions to clear up anything. Thanks!
