This is a short card, and there is no power connector to the card. Fan works on the card. It came installed from the factory. I suspect the card wasn't fully seated, although I have not had to remove it. But I have not tried it again. She's happy with it as is for now, so I'll try it again next week while she is at work.
How do I know if I have a bad video card? I upgraded my wife's XPS 8930 with a new SSD and in the process did a clean installation of Windows 10 Pro. Today, the computer did not appear to be booting so I suspect she turned it on and off a few times. When I looked at it, it was powered on and seemed to just have a blank screen. No video. Unplugging and plugging in USB devices produced the familiar tones as if Windows was running. Soundbar was powered. Green light on the back was on. Keyboard numlock/capslock on/off okay. Unplugged/replugged HDMI cable and nothing. Plugged it into the onboard graphics HDMI and nothing. Removed the video card and plugged into the onboard HDMI port and everything worked. [URL] Found this (page 3 of the thread) about "Secure Boot" not supported. Is this my problem or is it the video card? If it is the video card, or if not having secure boot is really bad, what video card is suggested. She wants to drive two 4k monitors. Thank you.
XPS 8930, added SSD, now no video
