It dosent post, the fans spin on the gpu. the power supply is the 245w from the dell optiplex 380. I also tried a external psu too, and that didn't work either. Yes i plugged the hdmi into the gpu. wym former and later? I only have this one gpu to test. I bought it used and it said working.
So I followed the the $150 gaming PC build (https://www.youtube.com/watch?v=J8ja79SlA-g). I did everything the video said, And my PC boots. However as soon as I plug in the graphics card there's no boot. The graphics card is a gtx 750ti with acx cooling. I figured it might be a psu wattage issue so I used a different power supply. Still no boot. pls help. Reddit didn't...
