B550-f gaming (wifi) post issues

[Talisak]

Looking for help

I have been fighting an issue with my pc for several months and I'm running out of ideas.

The pc will not post and sits on the white qled, this is very intermittent however.
If I reboot using the reboot button, it will post after 3-5 attempts. The pc runs without any issues once posted, and sometimes will even reboot fine without issue.
I have replaced the CPU, Ram, and PSU based off of others with similar experience but nothing has corrected the issue.
I've unseated and basically rebuilt the pc several times.
Any ideas out there? Thanks in advance.

The specs currently are:
Strix b550-F wifi (bios 3611)
Ryzen 9 5950x (-0.05 voltage offset, have tried at default to no avail) -Previously a Ryzen 9 5800x - same issue
Corsair H150I elite AIO
Corsair 4000D Airflow case
Corsair Vengeance 64gigs (2x32) at docp 3600 (have tried with no docp and at lower speeds, no improvement)
Corsair Shift RM1000x (upgraded from an rmx850)
Rog Strix 3070ti OC (no other gpu to try)
Samsung 980 1tb nvme

Update: I've chatted in with support and was given the standard  troubleshooting tips. Nothing fixed it. I was then told my GPU is incompatible with this motherboard (I'm not kidding). At this point I just want to know if it's the motherboard or the gpu, and if anyone else has RMA'd these devices with any kind of success. Or even better, has anyone found a solution?! Support are you here? I've seen this issue posted in multiple locations so it has to be something with this board, but none of the tricks I've read work.

disable CSM and fast boot ! and make sure your running your gpu and nvme drive on the same gen ...if you got a gen 3 nvme ...your gpu must also be set to gen 3 it dont matter if its gen 4  ..... UNLESS you put the NVME in the slot that has its own controller ....i have a Asus crosshair VIII Formula ..... had the same weird stuff going on my board has two nvme slots ....and only one of these slots runs on the pcie lans ....and if the gen 3 nvme is in the pcie lane slot and i ran my gpu at gen 4 ....i couldnt boot ....and if it did ..it would soon crash .... so gen 3 everything even the chipset ......you have to if you got the gen 3 nvme and its in the pcie lane slot
