I just finally built my new computer, but I have run into some problems. Whenever I power my computer on, everything starts except my GPU. Since my monitor goes through the GPU, I can't see anything in my BIOS. I know this GPU does work because it was in the old computer and is just temporary until I get a 1080. I also tried using a GTX 650ti from an old setup and it wasnt working either. Any thoughts?
