Red CPU Light after AMD Driver Installation

[AM5User]

Building a new AM5 machine. In short (!), as soon as I install AMD drivers the screens go black and the red CPU light on the motherboard lights up. Then, when the machine is booted it'll get to the Windows logon screen for a few seconds and then die. If I boot to safe mode and remove the drivers I can then boot the OS normally and it won't happen again (until I try and install AMD's drivers again).

• The motherboard's LEDs cycle through and completely go out during post
• Happens across multiple OS
• Happens across multiple AMD driver versions including the motherboard manufacturer supplied drivers (the AMD driver installation package lists both the iGPU and installed GPU)
  • However, Microsoft's AMD driver from Windows update (31.0.12027.7000) is "stable". I was able to run 10 minutes of Cinebench with the expected results with this GPU driver
• Happens with both iGPU by itself and a dedicated GPU installed
• If I disable iGPU in the BIOS it seems to happen sooner in the boot process
• I've tried outside of the case, to check for shorts
• Reseated everything and tried a different CPU
• Can't spot any issues with the motherboard physically
• Power supply is quality 850w and I'm testing barebones so load is very low
• CPU temps are fine
• When this happens the power button on the computer does not work, I have to turn the system off by the PSU switch (Power button works as normal otherwise)

At this stage, fairly confident it's a faulty motherboard but has anyone come across this before? Feels like as soon as the iGPU is "engaged" with the AMD driver it hard fails and kills the system.

Gpu drivers ? And do u have a gpu or just using igpu ?

Yes, GPU drivers. It happens with no GPU fitted and with a GPU fitted.

What GPU? Considering that drivers start actually utilizing a GPU's functions, it may be an issue with the GPU.

 

Please also realize - mildly unstable DDR5 configs will destroy your windows install, and can cause all sorts of issues. Turn off EXPO, go to windows and run this command in cmd prompt as administrator:

 

DISM /Online /Cleanup-Image /RestoreHealth

 

Then, run this:

 

SFC /scannow

 

These will fix any corrupt issues with Windows. The presence of errors is also a confirmation that you most likely have an unstable ram configuration.

It happens with the integrated GPU and dedicated GPU, but the drivers touch both so that makes sense. It happens without a GPU installed so I’m confident there’s not an issue with the dedicated GPU. 
 

Doesn’t feel like a memory issue at this stage,  as without the AMD drivers it’s stable and will run Cinebench etc… although happy to be told otherwise. I don’t have other memory to test unfortunately. 

 

I’ve also re-installed Windows, and the problem persists so happy there’s no issues there.

I’m having the same issue right now? Did you figure it out, Im about to just buy a new motherboard ?

I ended up returning the motherboard and purchasing a different make/model. Never got to the bottom of it.
