So here is what I know. I recently bought parts for a new computer. I put it all together and everything worked apart from the graphics card (Sapphire AMD Radeon HD 7850). I was getting no video output from all of the ports on the graphic card, the fans spun up, but my monitor did not detect anything, and when I looked in the device manager via onboard graphics, there was no sign of it there either. I moved the graphics card to the pci x4 slot on my motherboard (a Gigabyte Z77-DS3H) and it worked fine. At first I thought the pci x16 slot must be faulty, but when I put the graphics card from my old computer (a AMD Radeon HD 7750) into the pci x16 slot on the new motherboard, it worked fine. I have tried installing the drivers for the card while it is in the pci x16 slot but it could not detect it. My bios is fully updated. I tried disabling onboard graphics but still got no video output. I am relatively new to this stuff so go slowly with me.
So, any ideas?
