Hi. I recently built my own computer and am having issues with my gpu. Nothing seems to be working with it. I have made sure installation is right, but when I boot, I get no signal with the hdmi plugged into it. When it's plugged into my mobo, the z97 krait edition, the integrated graphics on the i5 work fine. In fact, that's how I installed all the drivers. AMD Catalyst 15.15 and 15.7 tell me that the "installation package failed." I just want my new gpu to work. Any help will be appreciated. Thanks!
