I just bought a R7 250 for my HP computer a6655f (if you wanna know witch one exactly), and I'm running my GTX 650 just fine, I read that my motherboard M2N68-LA Narra2 is compatible with PCI Express 3.0, but I cannot get any picture from it I have read good amount of threads on the matter followed some steps, set my BIOS and everything and I still can't get it to give me a display. I just simply want to know if I'm wasting my time, really. I don't see how this can't work in my system. Let me know you need any more details or info.
