Graphics Card Not Detected

Hello forum,

I need some help. I recently built a gaming PC out of these components:

ASUS ROG STRIX Z370-E motherboard
ASUS ROG STRIX GTX 1060 6GB graphics card
Intel i5-8600k processor
G. Skill Ripjaws V Series 16GB (2x8GB) DDR4-3200 memory
EVGA SuperNOVA NEX 650W 80+ Gold power supply
Cooler Master Hyper 212x cooler

I powered it on, and the GPU could not be detected. I've been trying all night to get it to work, looking in Device Manager, updating GPU drivers (which I can't seem to do becuase it doesnt detect an NVIDIA GPU), taking it out and putting it back in again (in both PCie slots) and it just won't show up. I set the BIOS to default and am considering updating it if that is what it takes, but I would prefer not to if possible. If anybody knows how to help, I would greatly appreciate their response. Thanks.

  1. hello there,
    first question first, if the GPU could not be detected, how are you booting to windows? on-board graphics?
    second, ASUS ROG STRIX GTX 1060 6GB requires 1x8pin connector, have you connect it?
    third, have you tried it in other PC?

  2. Turn it off. Plug the monitor into the graphics card. Turn it back on and try the drivers again.

  3. make sure your PCIE power cables are attached properly. 2 separate cables attached to it. not 1. you need to properly attach the 6+2pin in properly. make sure its properly seated. its a tight fit so make sure its seated properly and clip goes up. check your BIOS if it detects your GPU before you want to load it to windows. go to your advanced settings. PCIE. also go to SA menu. and check if the default of your graphics is set to auto/pcie.

    if it doesnt detect it. even if you saw your GPU fans running for a bit on power on. you may need to double check your CPU socket pins in your motherboard. if you dont find any of them bent. then your board or gpu may be faulty. double check on the version of your mobo as well if its the latest.

    I have been booting to windows through my motherboard because whenever I try to do HDMI through my GPU I get a black screen.
    I have connected the 6+2pin connector, and the card lights up so I know it is getting power.
    No, I have not tried it in another PC, but I plan to as soon as my friend builds his rig.

    I have tried that, it gives me no signal.

    Just tried setting display from auto to pcie, didn't make any difference. BIOS still doesn't detect my GPU. The card does have power as the lights are on, but I have yet to see the fans move once.

  7. have you tried using DVI cable? or the other HDMI slot (I assume you tried this one alr and tried using HDMI only)
    try cleaning the dust in the PCI-E slot?
    have you tried on using another GPU?

    since BIOS setting not helping, I think its your GPU faulty

    Make sure you dont have any monitor plugged into the motherboard when you do so, as it can disable the graphics card if it starts the IGPU first.
