Is a Ryzen 7 3800XT 8-Core Processor or a GTX 980 supported for mining?

I have a Ryzen 7 8-Core Processor and a GTX 980, and I can’t mine on either one of them. Is there a certain problem with either of them?

Make sure you have enough available VRAM as you start to mine on the GPU, and enough available RAM as you start to CPU mine.
