Hi, I'm trying to cobble together a gaming PC for my nephew, He's got a Lenovo ThinkCentre M91p and bought a GTX1660 GPU and a CX550M PSU, The GPU lights up and fan spins but no output, I try to open any thing Nvidia and it says no Nvidia GPU detected also under Device Manger I have no GPU under display adapters but under other devices I have PCI slot but can't update the driver or anything.
I tried the 1660 in another PC and it works fine. I put my working GTX980 in the Lenovo machine and same deal no out put but I can boot in to on board graphics even with the 980 GPU in but still no detection of the GPU. With the 1660 I couldn't boot in to the on board graphics with the GPU inserted, I'm pretty stumped, Any ideas? Maybe this should be posted in Motherboards, IDK but if any one can help me with this I'd really appreciate it.
