I’ve recently bought a gtx 1080ti gpu. I have an intel i5 8400 cpu, and four times four gb ram (Corsair vengeance). The power supply has 500w maximum input power. However, my new asus gaming monitor refuses to give me any form of image. It’s definitely connected to power since the red light at the bottom right is on. Can someone tell me what kind of errors I could have made when I installed my two new 4 gb ram today?
