I tried upgrading and it all went wrong

[Annatar]

System Specs

CPU - 2400G --> 5600 (from China)
Cooler - The stock AMD one to a Thermalright SE (£15 one)
GPU - 1060 6GB --> B580 (unopened)
RAM - 24GB, 2x8gb Corsair LPX 3000mhz in the main slots, 2x4gb Corsair LPX in the secondary slots
MOBO - Gigabyte Gaming AB-350m. I updated it to F53g and I think F52 for back up bios
PSU - EVGA 550 G3

So I have built 2 pcs before so I'm not a total newb to it. I will just state what I did. So I updated my bios to F53g which I believe supports the 5600. I ran a stress test to heat up my 2400g to make it easier to remove it and the stock cooler. I removed them and installed the 5600 and installed the new Thermalright SE cooler. My PC would then ask me for a bitlocker code which I didnt know at the time as it was a pirate copy. It then turned itself off. Then I rebooted and it turned itself off again at that part. So I booted into BIOS and it stayed on. I checked to see if I could adjust ram speeds and stuff and tried XMP. It was fine. I thought maybe it was turning itself off at Windows because I installed the cooler wrong so adjusted the Fan Curve to max. Then I left and same problem.

I took the CPU and cooler out and made sure I put them in right. Same problems. Then I thought I should try my old CPU with the new cooler. Now I'm getting no signal on my monitor. I removed my 1060 a few times when putting in the cooler so I'm thinking ive broken it. Okay I will try the integrated graphics still no signal. Then I try clearing the CMOS by shorting the two pins on my motherboard and now it just keeps restarting itself.

Is this recoverable? What should I do next? I feel kinda defeated at this point and thought I should just send the 5600 and B580 back but even then now I have no pc instead of the 2400G and 1060 I had before. Tried to upgrade and ended up worse than before

So you can’t get to bios with your old cpu any more?

Go back to basics. Remove GPU. 1 stick of ram. Boot drive. No peripherals other than keyboard and mouse.

I cant get a signal to the monitor so I don't know if it's going into BIOS. I doubt it as it keeps restarting itself now.

It boots then after 5 seconds restarts

1 stick of ram and take out gpu and try.

Will give it a go tomorrow and report back

Try removing the battery from motherboard for a while and try GPU in another slot. Did you get a message to press Y or N for new CPU? Just hit Y.

"American Megatrends
Version 2.20.1271. Copyright (C) 2024 American Megatrends, Inc.
BIOS Date: 09/02/2024 Ver: F53d
Press <DEL> to enter setup.

New CPU installed, fTPM/PSP NV corrupted or fTPM/PSP NV structure changed.

Press Y to reset fTPM, if you have BitLocker or encryption enabled,
the system will not boot without a recovery key.

Press N to keep previous fTPM record and continue system boot; fTPM will NOT
enable in new CPU, you can swap back to the old CPU to recover TPM related
keys and data. "

That's what it said when I put in the new CPU. Then I clicked Y and it went into windows asking for the BitLocker code. I went to check it but the PC kept turning off on this screen. But it would stay on when in BIOS. I probably at this point should have just installed a clean copy of Windows from a bootable USB. But instead I thought it was a hardware issue so put in the 2400G. Then it stopped giving a signal to the monitor. Then I tried clearing CMOS with the two pins on the motherboard but it just keeps restarting itself and still no signal.

Going to take a look at it again tonight. Hope the motherboard isn't bricked.

This is by design, after a period of no keys being pressed on the BitLocker screen the PC will shut down

Omg I wish I had known this before. All that headache and messing around because I thought the CPU was overheating on that screen or something.

I think when I go home tonight I will try firstly...

1. Remove the 2400G and put the 5600 back in and see if that stops the endless reboots its currently doing. If that works and I manage to get into BIOS I'll just do a fresh windows install with a USB drive.

2. If that doesn't work I will try disconnecting the RAM and trying 1 stick along with the 5600 + 1060.

3. If that doesn't work I will try 1 stick of RAM with the 2400G with the integrated graphics (Remove 5600 and 1060).

4. If it still isn't working I will try to remove the battery from the Motherboard and reset CMOS. Although I've never attempted to remove a battery before from a MOBO and it does look quite stuck in there. Then I will try it with the 5600 + 1 Stick Ram and 1060.

5. If none of that works then accept defeat and return 5600 and B580

good plan
and check if any socket pins are bent or maybe a piece of thermal paste fell in the socket while at it

Will do. One question I have is my motherboard is the Gigabyte Gaming AB350M

https://www.gigabyte.com/Motherboard/GA-AB350M-Gaming-3-rev-1x/support#dl

It has dual bios and I updated the main BIOS to F53g. The back up bios I updated to F52.

With all my tampering I'm not sure if it has gone back to F52 when I was clearing CMOS and stuff by shorting the two pins on the motherboard. Does F52 support Ryzen 5600?

Also when you clear CMOS is that what it does? Rolls back to the back up bios (F52)? or does it just clear the settings for the current bios (F53g)

From ChatGPT:

Spoiler: ChatGPT

After you:

• Installed the 5600,
• Pressed “Y” to reset fTPM,
• Then swapped back to the 2400G,
• Then cleared CMOS manually…

…the board lost track of which BIOS copy to use and also wiped its POST memory (RAM training, fTPM data, and PCIe initialization).
Gigabyte boards sometimes get stuck in a boot loop at this point — constantly restarting while trying to retrain memory or resync BIOS states.


Since both BIOS chips are updated and compatible, you’re in a recoverable state — it just needs a full, forced reset of both BIOS environments.

Which essentially confirms what we're saying.

"Since both BIOS chips are updated and compatible, you’re in a recoverable state — it just needs a full, forced reset of both BIOS environments."

So is this saying my first step should be to remove the Motherboard battery and short the pins? Then try it with a 5600 + 1 stick + 1060

 

[Annatar]

So I took out the Motherboard battery, shorted the pins, inspected the 5600 carefully and put it in, put in one stick of ram in the second slot from the CPU. It seemed to start and restarted maybe one or twice. Now its just running but still no signal to the screen.

The keyboard light is on so I think it is working apart from the signal...not sure what to do

 

[Annatar]

That's with a graphics card, right? I assume you're aware there's no graphics with this CPU.

Yeah right now I have a 5600, 1 stick of Ram and the 1060 6GB. I've tried both HDMI ports on the 1060.

I think the PC is in BIOS in the background because the cap lock button lights up the keyboard. So the main problem I think is fixed its just not getting a signal.
It's a Asus 1060 6GB expedition and the indicator light on the power connection is white (it turns red when the power cable is removed). So I think it's alive...? Confused!!

Kinda debating whether to open the B580 and try it with that...

 

[Annatar]

Good news guys. I tried it on a 1080p TV from 2007 and it displayed the BIOS ( I was trying it on a 4K Asus monitor before)

So next I can add back my cable for the SSD and then install windows from a bootable USB right. And once that is all done I put in the rest of the RAM sticks?

 

[Annatar]

Did you sign in to Windows through a Microsoft account, or have a Microsoft account linked to it? If so, you may be able to retrieve the key from that account.

I managed to find the key. Everything seems to be working fine now. Stress tested the 5600 and put in 2 sticks of Ram and enabled XMP.

Think I will leave the B580 for tomorrow.

Thanks everyone for the help. A great relief that its all worked out
