I got my new Graphic Card "ATi Radeon 4550" to work. But the problem is that i don't think i can download the Drivers for it because of my OS. The Screen can only handle 1600x1000 Resolution. I can't make it bigger. And it just doesn't look right for the Graphic Card. I tried downloading the Catalyst Center Panel. But it gives me an error saying that i have not settings activated or something like that. When i try and download it from the Dell website it says my OS is not supported. How can i download the drivers for this Video card manually? If i can't how can i go back to Win7. i deleted Win 7 on my PC because it was wasting alot of space and i liked Win10 but i didnt think about this. Thanks!
