Hi I'm a real noob at pc build it's my first time and I have a pc that I just built and the graphic cards spins for like 2 secounds then turns stops spinning when it boots it's a 1050ti co 4gb. I plugged the hdmi from the graphics card into the monitor and it works and I also went into the device manager and it's doesn't show my gpu? And when I try playing overwatch it's super laggy. The worst help?
