Asus Crosshair VIII Hero Crashing

So my PC has started behaving pretty badly, and just wanted to make sure I'm not being an idiot in thinking it's the mobo at fault...

CPU is a 3950x (Cooled by a 360 AIO)
Mem is 32GB (4x 8GB Corsair Vengence RGB 3600)
Mobo BIOS is up to date, and running default settings - I've tried with and without c-states disabled
PSU is a Corsair AX1600 - I didn't buy it, this is a warranty replacement from a smaller unit I was sent because they were out of stock of smaller units.
GPU is an MSI Suprim X 3090

Running Windows 11.

 

The computer randomly crashes, and it's been happening more and more frequently. It's always when the PC is pretty idle, or I'm doing something light like web browsing or messaging, never when gaming...
Looking at monitoring tools nothing is getting too hot, and I haven't witnessed any voltages getting too low.

When crashing... The screen will sometimes retain the last image, and sometimes go black, it's pretty random.
The power button locks up, holding it for longer than 10s won't turn the power off to the PC.
The reset button stops working (yes they are wired up correctly).

 

Event viewer shows absolutely nothing at the time of the crash.

So new mobo time??

Try running Memtest64 on your RAM. 3600mhz is pretty high for 3000 series, especially 4x8.

Ram would be the first suspect indeed. Do you have the Ryzen specific Corsair modules (with m2z / m4z in the name)? The regular ones dont play too well with ryzen.

Been running fine for over a year and only started playing up in the last month or two...

So I got rid of DOCP and I'm just running the RAM at 2666Mhz...

 

Memtest64 didn't show anything at this speed, I didn't run it at 3600Mhz.

 

However the system has been rock solid since Monday, so it must be either RAM, Memory Controller, or something on the motherboard that doesn't want to work at 3600Mhz any more...

 

Either way, good shout on it being Memory related, major thanks to both @Skiiwee29 and @Sjaakie!!
