Cpu upgrade issues

[Jac m]

Hi. I bought a used Ryzen 4500. I was trying to replace my 1500X. I updated the BIOS in my Gigabyte AB350M motherboard. I installed EC FW Update Tool (B19.0517.1). Then, I started the BIOS updates with F21, then to F31, and lastly F51d. After all of this, I replaced the CPU, and I can get it to post and work in the BIOS, but not load into Windows. It will try for a few seconds, then black screen. I can't get Windows to load into safe mode. Any thoughts?

Hi, try this
Put the old CPU back > boot into Windows > update the chipset drivers.
Re-flash the Ex firmware
In the BIOS, reset to defaults, disable EXPO/DOCP and turn off fTPM and secure boot. 
Swap in the Ryzen 4500 and try, if still blackscreens then run a clean Windows installation.

I tried running Linux off a USB, and it did the same thing as Windows. The only exception was that it allowed me to interact with the install window. It even let me run a memtest86 test, and it passed. I did update the EC FW following Gigabyte's instructions. Is this the same as the chipset drivers?

Hey Jac, thanks for the update

The EC FW tool you mentioned is not the same as the AMD chipset driver,  they’re completely different things.

EC FW update > updates the embedded controller firmware on the motherboard.

AMD chipset drivers > update Windows’ low-level drivers (power management, I/O, scheduler).
 

When you swap from a 1st-gen 1500X to a newer Ryzen 4500, Windows is still using the old driver stack. That alone can prevent booting.
 

Here’s the only way to rule this out I can see now :
 

Put the 1500X back in, boot into Windows.
Download and install the latest AMD Chipset Drivers 
Shut down > swap in the 4500 > boot and test.

If you still can’t get into Windows, > try a fresh Windows install
