EVGA RTX 3080 FTW3 Not Fully connecting after MOBO/CPU Upgrade?

[S2KTom]

So I recently upgraded from a 7700k/Z270 to a 13900kf/Z690 Dark KPE all with a fresh M.2 windows install.

Now I can't use my 2 monitors, only 1 fan is spinning on the gpu, and in Precision X1 it doesn't show ANY movement in the memory clock, GPU clock & voltage, power target is automatically set to 26, and gpu temp is 0, when I go into the VF curve tuner and press scan, a window pops up saying "OC Scan only supports primary card!" even though I have only 1GPU and it's in the very stop PCI-e slot.

All 3 fans go up to full speed when in the bios loading screen, but when it gets started on launching windows, 2 of the fans stop spinning almost like windows is telling them to

I've updated and installed all the drivers required for my cpu, mobo, gpu, etc. as far as I can tell, and yet it seems like the mobo isn't fully accepting the GPU and I'm not sure what to do next. I've reseated the riser cable and GPU 3 times now and still no fix.

Before I upgraded I didn't have a single issue with this ever, but for whatever reason I can't seem to fix it

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU as well, apart from it's make and model.

Did you manually install your GPU drivers in an elevated command, with the latest drivers from Nvidia's support site as opposed to letting the OS source the drivers? If not, then use DDU, then install the latest driver by Right click installer>Run as Administrator.

Apparently both of my riser cables were bad, I just didn't know it before I went to sleep, I woke up and immediately knew what it was somehow. I put the card directly into the mobo slot and it's working perfectly
