Motherboard doesn't recognize GPU

So this is my first custom build and everything went smoothly until I realized the mobo (ASRock Z87 Pro3) didn't detect my GPU (EVGA GTX 760). So I figured I would install the NVIDIA drivers, whose program promptly read,"you need a NVIDIA GPU...". I don't think the power is an issue, as the fans to the GPU turn on whenever I power up the computer.

I've went into UEFI BIOS and all the settings in there should be correct - Primary Graphics Adapter: PCI Express, iGPU Multimonitor: disabled. However, the System Browser detects nothing connected to the PCI-Express 3.0 slot, although I've remounted the GPU numerous times, and cleared CMOS by removing and placing back the battery.

The last thing I need to do is to test another GPU in the slot and try my GPU on another mobo to determine who's at fault here. In the meantime I'd like suggestions for anything I should try, don't be afraid to mention obvious reasons as this is my first time.

Build
CPU: i5-4670
RAM: 8GB
GPU: EVGA GeForce GTX 760 2GB Dual Superclocked ACX
Mobo: ASRock Z87 Pro3
Storage: Seagate Barracuda 2TB 3.5" 7200RPM
PSU: EVGA 650W (http://www.newegg.com/Product/Product.aspx?Item=N82E168...)

  1. Try another pcie slot.
    Double check per - http://www.tomshardware.com/forum/261145-31-perform-steps-posting-post-boot-video-problems

    Could be a 760 or mobo problem.

    Post your build. Could also be a power supply problem.

    Double check your mobo, gtx and power supply instructions.
  2. Update your board's 'Bios' by goignt o Asrock's website. You might also want to check the forum and make sure there isn't a conflict. YES there can still be a power issue, check again how many watts and what your 12V Rail is against the demands (I think 650W is what it needs).

    I tried to do that, but as I went into Instant Flash (after formatting to FAT32 and DLing the newest BIOS), nothing came up, which I think means it's the latest version.

    EDIT: I forgot to extract, just flashed and am going to restart a few times, then go into BIOS

    This mobo only has one pcie :(
  6. Could be that you've got same pcie 12v rail plugged in - only 20A per rail available. For a 760, 30A min is needed. You need to make sure each connector is from a different 12v rail.

    We recommend using single rail 12v psu's just for this sort of problem. eg Antec HCG 520M

  8. The photos don't help. Make sure your'e using a different rail for each power supply connection to your 760. Or get a single rail 12v psu preferably - http://www.tomshardware.com/answers/id-1804779/power-supply-unit-tier-list.html

    I have a dumb question: how do I know if they're on the same or different rails?
  10. I just flashed the latest BIOS from ASRock, but I still don't see anything. I tried plugging the monitor cables into the GPU DVI ports but got no signals in both.
  11. http://www.evga.com/products/pdf/120-PG-0650-GR.pdf

    says its fully modular - so two separate cables from the power supply to the 760. Use one 6 pin connector from one cable and another 6 pin from the other cable.

    Isn't that how I have it in the first picture? Not trying to sound rude. I did try to change the slots on where the cables were plugged into the PSU (before it was VGA 1 and VGA 2, now I have VGA 1 and VGA 4)
  13. OK if two differenet cables psu to gpu, then should be OK. Not nice, but OK.

    The EVGA 650 psu comes up in Tier 4 (?) - http://www.tomshardware.com/answers/id-1804779/power-supply-unit-tier-list.html - "Not for overclocking systems or high end gaming rigs" So think about another.

    What monitor?

    ASUS VS239H-P

    EDIT: A friend (who doesn't live nearby) did nearly the same exact rig as mine (different case and slightly older version of same PSU). The difference is that after his build, everything went smoothly. He told me he just had to install some mobo drivers (I assumed the INF drivers from the ASRock site) before his GPU was recognized.
    EDIT: he used the exact PSU in your link. Mine was a bit different, the 120-G1-0650-XR.
  15. http://www.asus.com/Monitors_Projectors/VS239HP/specifications/

    The monitor has HDMI , D-Sub, DVI-D inputs

    http://www.evga.com/Products/Product.aspx?pn=02G-P4-3765-KR

    The graphics card has DVI-I, DVI-D, HDMI ouputs

    So what are you using?

    Have you checked connections are tight and the cable is in good condition?

    I would use hdmi to hdmi or dvi-i to dvi/vga adapter to D-Sub

    So I've been using the DVI cables that came with the monitor, alternating between the DVID and DVII connections to no avail. I've been thinking about trying an HDMI, but that's still shipping.

    Shouldn't the GPU appear the UEFI system browser though, since it's connected and powered?
  17. OK - you need to use a DVI to VGA adapter on the graphics card - http://www.ebay.com/sch/sis.html?_kw=DVI+VGA+Adapter+Connector

    on the DVI-I port - http://en.wikipedia.org/wiki/Digital_Visual_Interface

    and run the vga cable from the adapter to the D-Sub (VGA) port on the monitor.


    Edit - No, the card is not within the realm of the motherboard. The card is controlled and monitored with say Afterburner.

    I plugged in the cables and booted up, but still no signal. Will the HDMI be any different? But the card is connected to the mobo, isn't it at least supposed to be detected? A lot of tutorials I saw expected it to be under "Device Manager" listed under either "Display adapters" or "Other devices". I'm getting zero awareness, like there is no card.
  19. Best answer
    It should be listed under Display Adapters. Sure it's plugged into and locked into the top pcie slot?
  20. Nothing under display adapters except Intel HD 4600. I'm sure it's plugged in properly and in the top pcie slot.

    EDIT: I screwed it in and everything. The only way to test this, is to try the GPU on another mobo. But is there anything else I may have forgotten?

    UPDATE: I tested another GPU in the same slot and the PCI-e appears to be working fine. Going to test the GPU on another mobo soon.
  21. So, did it work..?

    Don't post to NECRO threads, no one is reading a year old thread that was answered.
    The issue seemed to narrow down to
    A) the PSU wasn't as capable as a friend / nor as i7Baby pointed to, so logically he doesn't have the right PSU (so lower end cards would work but not a 970)
    B) that the GPU works in another system or not, again still needing to meet power demands from the 2nd system (usually they test them back at the store on a high end rig they have or with a high end PSU they test with to ensure for all devices enough power is capable)>

    Would still be the same answers for your case.
