I have finally put together a build from OzBargain deals over the last few months:
MSI B650i edge wifi
RX 7900 GRE GFX
AMD R7 7700 CPU
Corsair DDR5 32gb 6000mhz cl30
Corsair SFX 750w PSU
Lexar 4tb m.2 SSD
Peerless Assassin CPU cooler
NR200 case
With the GPU out of the machine, the PC posts and runs on integrated graphics fine. Windows, chipset and other drivers installed. Also flashed bios to new version. However, I can't get a display out of the GPU, and I am suspecting the entire PC wont post when the GPU is in the Pci-e slot.
I've tried multiple PSU cables, reseated the GPU, swapped the RAM around and tried on only one RAM stick.
The debug lights (CPU red, DRAM yellow) on the board do light up when the GFX card is installed. But there doesn't appear to be any actual issue with the ram or CPU.
Is my GPU dead? Or perhaps a faulty PCI-E slot on the board? I appreciate your thoughts!
EDIT SOLVED - backdating bios to a version that has AGESA ComboPI 1.09.0 solved the issue and allowed my graphics card to be detected by the motherboard. The relevant bios version for the B650i Edge Wifi is 7D73v16
You can try searching Google or your motherboard for exact error codes or flashing lights signal - is this post linked similar to your issue?
