Hey there. I just built my first pc and have installed windows etc. I had to take my gpu out and run from the vga port on my mobo to monitor to get any signal. (gpu didnt giive monitor any signal) So I finally got it working with onboard graphics and now when I plug in my gpu it isnt recognised? what should I do?
