Question Windows 11 - screen turns black and PC reboots - no error files ?

[Big123]

HI All,

I've recently built a PC and have been having problems pretty much everyday.

CPU: AMD Ryzen 9 7950X3D 16-Core Processor 4.20 GHz
RAM: Corsair Vengeance DDR 5 96.0 GB (95.1 GB usable) 6000Mhz (BIOS shows 4800Mhz not changed)
GPU : NVIDIA 4090
PSU: MEG Ai1300 watt PCIE5 MSI
MB: MSI MAG X670E Tomahawk
OS: Windows 11
No Overclocking

Everything was brought brand new.

Let me know if you need any other hardware information or in general any other information.

The main issue is, that this PC randomly reboots, I cannot for the life of me find any Mini dump or actual errors causing this in Event Viewer.

When I'm doing anything like gaming or just listening to music on YouTube, it will suddenly shutdown and restart, no "Restarting Now" is shown on screen just the MB starting up then into windows, No BSOD.

It usually does this once or twice a day,

I've stress tested the system with multiple different programs to try and incite a crash, nothing has worked, the most I was able to get the PSU was 704watts and it's rated for 1300.

I've even set the Pagefile to 97GB in order for Windows to dump all information from the RAM into an error log and it doesn't.

Any new ideas would be massive.

Welcome to the forums, newcomer!

No Overclocking
Not even E.X.P.O enabled in BIOS?
RAM: Corsair Vengeance DDR 5 96.0 GB (95.1 GB usable) 6000Mhz (BIOS shows 4800Mhz not changed)
You should enable AMD's E.X.P.O and see if the issue persists.

MB: MSI MAG X670E Tomahawk
BIOS version for your motherboard at this moment of time?

How are you cooling the processor?

Thank you for the reply;

Nope, everything bog standard, I made the machine so it didn't need overclocking.
I'm not sure if EXPO is enabled but I know I did a CMOS reset when the PC failed to boot, so if it wasn't enabled by default it wouldn't be.
I recently flashed the BIOS, around a week ago. (1.BO - AMD AGESA - 7E12v1A I think)
I'll enable EXPO now and see what happens.

My CPU cooling is MSI MAG Coreliquid 360R V2 AIO CPU Liquid Cooler.

When stress testing to try and incite this error (never crashed during a stress test), I've managed to push my CPU to around 78-80c I think, but that was only after a very long stress test.

When I went to enable EXPO, I only found the option for XMP profile 1, saved and rebooted, PC didn't reboot, had to hard reboot (button held down until power off), then didn't start for at least 60 seconds. But the RAM is now set to 6000Mhz, so it did succeed in enabling.
