The reply from MSI Member Center [sic] "Regarding your concern, this motherboard supports the CPU 3600XT since bios v3.0, you do not need to update bios, please install the CPU and other device to check, can the pc boot up? "

So, back to square one. The original problem was the computer does have power, but there is no POST beep and no graphic output to monitor or TV via HDMI.

I have informed AMD as well via the ticket.

I have downloaded MiniTool Partition Wizard (ref. https://www.thetechlounge.com/best-partition-software/). However, I have been unable to get the full 32GB. So, I am not sure if there is some trashware still installed.

The question that should be asked, why are you trying to flash the bios in the first place? What originally happened to make you want to try? I also had a thought, what if the bios you are trying to flash is already on there. Full system spec would be good too.

The reasons is in my Post #5 above: AMD asked me to flash the BIOS.

However, MSI in post #21 say it is not necessary.

Now, AMD have contacted me to do the following:

"Considering the system is not only failing to correctly POST but also apparently failing to correctly flash the BIOS, during this process we are unsure to which extent this may relate to the CPU, the RAMs, the motherboard or a USB stick problem, considering MSI having their own BIOS flash process, with the Tomahawk MAX also possible to be done without basic components.

With that being said, so we may isolate the source of the experienced further, please do the following:

  • Clear the motherboard's CMOS by removing the motherboard's battery for 10 minutes and placing it back again. - Click here to see how. Method 2.
  • Test the system with one stick of RAM at the time, in each slot of the motherboard. - If only using one, test it into different slots from it.
  • As you have suggested, try flashing the motherboard BIOS without the CPU + RAMs in place. Keep in touch with MSI Support to confirm the process was correctly done or a failure may be happening (due to the lack of red lights flashing, for instance).
With the above steps, we are able to more closely understand the source of the problem, while avoiding, for now, testing the CPU/motherboard into a different system as well.
If you still need our help, please provide us back with:

  • The above tests results and MSI reply/conclusion on the BIOS flash matter.
  • Any additional troubleshooting you have done, besides the suggested by us and MSI.
  • The model of your:
    • RMs, including its Part Number (P/N), which should be present at the sticker's side.
    • Power Supply.
    • Graphics card, including it's specific manufacturer and model variation (eg. PowerColor Red Devil, ASRock Phantom Gaming X, etc)."

So reading between the lines you had a problem getting the computer to boot after you first built it. So you contacted AMD first, then MSI. And now you have two companies trouble shooting the same issue but tripping over each other.

You are more or less correct. I had initially contacted the seller (Amazon) when I wanted to return the processor and GPU. They directed me to AMD first.

I am the unpaid product tester. However, I am certainly learning more about intricacies of builds; thanks to the forum posters here and some "graft" on my part.

Welcome to the cutting edge lol. You should try the basic build AMD suggest, I would also take the storage out as well. The less parts the better. Do you have another graphics card to test with? Also what debug light show now when you try to boot?

and MSI request:

"Content:
Thank you for your information, in this case, if the pc cannot boot up, please check the EZ Debug LEDs, how do these lights change when switched on? Would you kindly please refer to the suggestions below to troubleshoot the issue?

1) Unplug all the components and devices on the MB, and then reinstall the CPU, RAM (one piece), VGA card and power supply only. Please add some thermal gel on the CPU, and then reinstall the CPU fan correctly and tightly. Be sure JPWR1/ ATX_PWR1 and JPWR2/ CPU_PWR1 are connected to proper ATX power supplies to ensure stable operation of the motherboard. If there are 6 pin or 8 pin Power Connectors on your VGA, please make sure they are connected to power supply。

2) Clear CMOS (How to clear CMOS, you could refer to the manual) for a try.

3) If the problem still persists, please change the RAM with different RAM slot to check again."

I better get on and do it...🐙

I'm not sure what you mean, "28 and change is the full." could you rephrase or elaborate please?
With Hard drives and UDB Drives you do not get the advertised amount it is always less like a 5TB drive once formatted will only be about 4.6TB You tend to lose about 10% of the advertised capacity once formatted.

I know of several large Ironbark Gum Trees you can try and push over will be less frustrating i'm sure.

Well, apologies for the delay responding. I have been rather busy testing, videoing, corresponding with MSI, AMD and now Amazon.

Some videos for information: https://ln2.sync.com/dl/85fc7e8d0/25hmkhup-nymfwiu2-vkjnk93y-ycbgaypz

TLDR: Amazon are replacing the CPU (due Monday).

Longer version:

I did everything requested in Post #29 and more...

AMD stated: "I understand your concerns and regarding what's been done so far, the thing that sticks out comparatively to other cases is how the motherboard behaves.
That being said, only MSI could provide you with a correct answer on that, no matter what XXX or I could say. What we can confirm is that so far, we can't rule out the possibility of a CPU fault but so far nothing strictly prove a CPU fault. What would tend to prove that the mobo is faulty however is that it's failing to use the USB BIOS flashback.

Regarding LEDs, their function is indeed diagnostic but it's solely indicative of what seems to be the issue. We've had cases where CPU LED would light up but the CPU was just fine in another config. I even had one where replacing a memory stick would make the system work.
What I can tell you as a trained and experienced sys/network admin is that BIOS are usually not recommended as there's a risk that is usually not warranty covered from their side. However it's still released by the very same manufacturers (that would not recommend updating their very own BIOS for their very own product) and it really does improve system performance, compatibility and stability and even sometimes security.

In conclusion what i'm trying to say down the line is that when it comes to the CPU, we can only invite you to try it it another configuration: if said other config POSTS, the CPU would be out of suspicion.
Trying another CPu in the motherboard and have the system POST would most likely indicate a CPU issue."

MSI stated: "About the bios, we have checked your S/N before, the bios version of your motherboard is v3.7, this is the latest bios version, you do not need to update the bios."

AMD do not yet know MSI's response.

I summarised the correspondence with Amazon, and they eventually agreed to a CPU replacement after I pointed out that I had fulfilled AMD's request to try other configurations (already using the second, replacement MSI motherboard with the same lack of POST beep and graphics output). Furthermore, there was an absence of other proactive solutions by AMD such as "take the CPU to XXX independent computer specialist", or "return the CPU to us to test" or "we are sending you another CPU to test".

Thanks for all your replies and suggestions. I have an Ironbark tree resistant forehead.
