Second Nvidia card not detected in Device Manager?
Relevant Specs:
Motherboard: GA-Z77X-UD5H
VGA: EVGA GTX 670 x2
PSU: SeaSonic X750 Gold 750W
So I've had one 670 for a while now, and it's worked great. I ordered a second 670 and a larger PSU. I hooked everything up, booted up, enabled SLI, and started running some tests - Heaven Benchmark 4.0.
It was going smoothly for about 5-10 minutes then my computer crashed. I rebooted and neither Device Manager nor the Nvidia Control Center would detect the new, second graphics card.
I took out my old, working graphics card and attempted to test the new one on the three different express card slots. It wouldn't work on any of them. I removed all the drivers with Driver Fusion, rebooted, reinstalled up-to-date drivers, but it still wouldn't work.
The fan works, but I know that's not an indicator that the card does. Is my card dead?
Dylan Armoogum - Yes you can.
