Yet Another GPU Not Detected in Bios

My friend recently upgraded his PC and gave me his old case, motherboard, and CPU. I had an already working computer, so I swapped my GPU, PSU, HDDs, RAM, and DVD drive into the new case, plugged everything in and turned her on.

Video outputs out the integrated graphics, but the new card, GTX 970, PCI-E, is not even read by the BIOS. Obviously, not the device manager in Windows either. I checked cables, reseated the card, and checked for any wear or damage on the card. Everything was top shape.

I fiddled around in the BIOS, reset it, reset the settings, reset the CMOS (battery removal overnight), still a black screen when I boot with the HDMI cable attached to the PCI-E video card.

Went into the BIOS and changed the settings to disable the onboard GFX. The computer only beeped at us to tell us there was no usable video to display.

My friend took his old AMD R9 video card and plugged it in with the rest of my hardware in it. The computer booted just fine and displayed via the R9. No problems. So it looks like the PCI-E slot is good. Reset the BIOS to display the onboard if primary.

I reassembled my old computer and booted it. Everything ran like it used to. Video displayed from my GTX 970. Looks like the GTX 970 is fine.

Reassembled the parts back into the new case with the new mobo/proc. Bought a new SSD, put Windows 10 on it. Ran the computer with only that HDD. Same results (no detected GPU).

Bought a new PSU. 750W. Installed it. Same results.

Now what? I'm absurdly stumped.


Here's my specs:

Proc: Intel i7 2600k
Mobo: Intel dh67clb3
GPU: EVGA Nvidia GTX 970
HDD: SanDisk SDD (though I have two Samsung Evo's with Win 7 on them I tried too)
PSU: EVGA GQ 750W Gold

Have you first uninstalled all previous GPU drivers completely using DDU, THEN installed the new GPU and drivers? Your issues is a common occurrence with driver conflicts, especially moving from AMD to NVIDIA and vice versa.

Is your BIOS updated to the latest version?

BIOS is updated with latest version. Using new HDD so there are no previous drivers. Used DDU anyway. GPU still not detected by BIOS.
