Hi I just got my first gpu it's a 570 hd sc and after I installed it into the PC and turning on my PC for the first time with the gpu plugged the resolution was soooo bad worse than before..also it looks like I have windows basic I can't change my tab colours I tried to change my resolution and I was really limited I have no idea what I'm doing and before I installed the gpu my computer looked a lot better so I'm kinda upset because I just sold my console wanting to go to PC. So please if you can help me out that would be more than appreciated
