My board ASRock H110M-HDS only has one pci-e slot so haven't tried that yet.Thank you broken cross. Is there anything else I missed or didn't do?
Let me just see if I'm getting this right. You have your monitor connected to the card and you seem to get an image. The only thing you are unable to do is find the card on the device manager. Right?
The only things you can do, seeing as you only have one PCI-E slot is:
1- Go to the BIOS and make sure your integrated gpu is turned off, reboot and then see if it detects it (it probably is already turned off, since there's no interface connected, but you never know)
2- If possible try another card on that same board, if Windows detects it, the card is probably a dud and the motherboard is fine
3- If you have access to another PC, try installing the card on it to see if Windows detects it. If it doesn't the card is the problem.
