Question System crashes, alternating CPU / DRAM LEDs flash on Aorus B450 M

[Pennine_Lad]

Hi folks

Some insight appreciated if possible into an intermittent crash of a pre-built sytem, no upgrades.

Fault: Boots up to Windows 11 (or Windows 10 on another drive), a few minutes to a few hours fine, then black screen and system shuts down. CPU/DRAM LEDs flash on motherboard.

Been used for light business type use, no heavy gaming.

System: 2019 pre built Chillblast Fusion, no upgrades. Worked fine until recently.
Aorus B450M, Ryzen 7 2700,
2 x 8GB DDR4 RAM,
NVIDIA GeForce RTX 2070,
250 GB M.2 SSD,
Corsair TX650M PSU

Tried but no effect:
All cables checked reseated,
CPU reseated, repaste CPU and GPU,
BIOS upgrade to F61 from original F40 supplied by Chillblast,
CMOS reset,
GPU driver updated,
Both RAM swapped to second channel, then just one of each 8GB tried first channel.
When stable for a while a CPU / GPU work out with a protein Folding@Home app shows no undue temp hotspots with monitoring software.
Fans all spooling.

Thanks for any help!

Corsair TX650M PSU
Might want to see if running the system with another PSU of similar quality and wattage changes your experience.

2 x 8GB DDR4 RAM,
Can you pass on the make and model of your ram? Ideally they should be on slots A2 and B2 on the motherboard.

Did you flash the BIOS to the latest recently? If so, perhaps try and perform a clear CMOS and see if the issue persists.

Hi

Thanks for the suggestions. I don't have a spare PSU to check at present. I did flash the BIOS with the latest from the builder and a CMOS reset.

I've just discovered Windows 11 Reliability Monitor and hangs after this 'Hardware error'. A quick Google suggest maybe GPU driver related but this was happening with original RTX 2070 driver and now with the latest one from Nvidia so not sure if is that. Will check the RAM maker.

Thanks, David

Update. The system is completely unstable for Windows 11 on the M2 SSD drive, booting to Windows but then crashing shortly after. Using DDU to clean all GPU drivers then reinstall made it the most unstable so far. Booting in Safe mode is stable.

It is completely stable if boot up Windows 10 on the SATA drive. Suggesting software not hardware. A clean Windows 11 install may be best approach rather than trying to isolate a driver conflict etc.

How does Windows 10 or 11 use a GPU if NVidia driver disabled or uninstalled as system is then stable from black screen crashes?

Does the instability if reinstall NVidia drivers either latest or older suggest a GPU hardware fault in the part the basic MS driver does not use?

A separate drive using Windows 10 has always been stable and realised this may be because an NVidia driver was never loaded it is using the Microsoft Basic Display Adapter. If install an Nvidia driver this also becomes unstable.

Thanks for any insight!
