Your GTX 780 is showing artifacts, and you're checking if the issue is with your system or the hardware. Since you're trying to test it on a 780i but it's not posting, consider verifying your graphics settings, driver updates, and network connection. If the problem persists, the hardware might need inspection.

What CPUs have you tested? Are the threefold processors supported by the motherboard, and do they match the socket or motherboard specifications? It might be a defective motherboard (socket) instead of faulty CPUs.
No bent pins were found and every CPU was tested on the motherboard prior
It might be a power-related problem too—have you tried using them without any GPUs installed?
I've tested two PSUs, both performed well. I've also used them without GPUs and with around six different GPU models.
FF doesn't always indicate a completely dead CPU. It might also point to a fault with the motherboard itself. MSI boards can display this if there are failed MOSFETs in the VRM circuit. From my experience with those boards, that's what occurred with one I owned—my CPU was still functional and operational today (MSI 790FX-GD70 with an 1100T CPU). I reviewed the original poster’s profile and saw they use a Gigabyte board, but it could still be another factor. If the CPU isn’t working, the board will detect it regardless of the reason. I recommend testing another board; it’s unlikely three CPUs would fail like this. If they did, it suggests something else was responsible, probably the motherboard itself.
