I have a Tomohawk B550 that die suddenly. No BSOD, no weird sign or no POST/boot just a day before it happened. Fans are spinning, BIOS had flashed several times, CMOS cleared, battery removed, etc. CPUs--5600 and 3700X were tested working on 3 other boards--Aorus X570/Auros B550M-Pro-P/TUF X570, so as the PSUs--RM650x/HX650 , as well as the DRAMs, all components are tested working. The only indicator it show was DRAM LED kept lit up, no beep. The same symptom also happen on my 9 years old TUF X99 board but thats another topic, probably due to age.
Today I bring out the board to check for the BIOS chip location as I was going to remove the chip to re-flash outside the board. Can't actually find it, unlike older boards, they don't located near the right bottom corner anymore. Could it be the WInbond chip located between the main M.2 and CPU socket? Anyway, I found 2 damaged chip/components! They ae located just behind the primary x16 slot locking clip, I must have chipped them while using screwdriver to remove the big@ss GFX card! if I'm not wrong, the tR68/2047 marking should be the inductor, for the power to x16 slot? And the other one with BDVM/616, I really have no idea what is it. I believe the inductor might still work but NOT the other with BDVM marking.
Please advise.
