Help GPU unrecognized by MOBO again?

Iknothtfeel · Dec 19, 2016

Hello new to the site and would appreciate help from all you great and knowledgeable guys out there. Currently just built my first new PC following all instructions to the letter, but my GPU can't be found at all either in device manager or during driver installation from Nvidia's Site leaving my monitor blank/black(no signal) when plugged into the GPU.
The card lights up and the fan spins. Intergrated graphics is the only place I can boot from.
So far, after scouring every forum on google it only yielded negative results. If anyone has something else I haven't tried the help would be greatly appreciated.
I've taken many steps to troubleshoot it myself as many people seem to have the same issue.

*I've updated all BIOS, Windows, and Drivers with no luck.
*MSI BIOS is supposed to auto detect the GPU so there's no way to disable/switch from the onboard graphics.
*BIOS graphics is set to PEG(only other choice is IGD) and Multi monitor is still disabled.
*Reset CMOS no luck either.
*Tried my older GPU(Gtx 960 4gb) in the new PC no luck. However both GPU's (gtx960,1070) still managed to work in the older PC.
*Tried interchanging the GPU's into both PCIE slots properly and didn't work.
*Changed hdmi cables no luck as well.

It looks to me like a MB failure, manual was of no help. Should I just go for an RMA?

System Specs: (All checked at PCpartpicker for compatiblity.)
Mobo: MSI z170A Gaming M5
CPU: Core i7 6700k
GPU: Asus GTX 1070 8gb turbo(new), Asus Gtx 960 strix 4gb(old)
OS: Win 10 Home OEM 64bit
RAM:2400mhz DDR4 Corsair
PSU: Corsair RM650X
Storage: 500GB 850Evo, 2TB SSHD Firecuda

Thank you.

Interesting. I am having a similar issue. I have the same motherboard, with 2 980ti's. If I play games with SLI enabled the PC will crash after a couple minutes, and on restart my bottom card won't be recognized at all. As if it's been disconnected in my device manager. It'll stay like this for a week or 2, then one day it'll just start working again. Been like this for over a year... back and forth, sometimes for months on end. Obviously the card isn't bad because it does work sometimes, the motherboard can't be bad either because it does work... sometimes. My theory is either a weak connection, a compatability issue with Nvidia and Windows 10, or a corrupt OS file that is causing problems.

Also, have you tried a clean driver install? If not, it's definitely worth a shot. if you're on Windows 10 go to control panel --> system and security --> advanced system settings. From here click the Hardware tab, open "device installation settings" and select No as the default option (don't forget to hit save changes).

Next, follow this guide: https://docs.google.com/document/d/1xRRx_3r8GgCpBAMuhT9... which will require this program: http://www.guru3d.com/files-details/display-driver-unin...

Thanks very much, tried but unfortunately no go. Still undetectable and still cant even install the driver itself. The only driver left seems to be the intel onboard.
