List all the exact model of your GPU, PSU and RAM for me.

For now disconnect all your HDDs, SSDs, and other USB devices that you have connected to the motherboard. Also try swapping different sticks of RAM in the DIMM_A1 slot only. Do not populate the other slots for now. Report back your results.

yeah, try disconnect all your PC part from motherboard and make sure it clean of dust, and connect again all your PC part. and see what's going on later.

Reflash your motherboard with the 0802 BIOS using the USB BIOS Flashback procedure for me. When the procedure is finished, power up your system. See if the problem persists.

Bios updated to 0802 but problem still persists,I tried already today with other bios versions nothing help

There is a red BIOS switch on the bottom right of the motherboard. Press it to switch to the secondary BIOS. Then start up your system. Any changes?

Interesting, I've encountered this same problem and it persists tried everything. It was working fine but started to notice motherboard wouldn't boot sometimes but a restart would get it work. Now it's gone completely. AF code, fans spin, CPU led lit.
