Alienware R15 AMD Desktop

Alienware R15 AMD desktop shuts down intermittently.   Did a clean W11 install a couple of weeks ago to try and fix this issue but it’s still happening.  

“Startup repair” is always unsuccessful with “Error: OS_BOOT_FAILURE”.   I’ll then launch “System repair” and that works.

The “Scan Hardware” diagnostic always comes back with “Everything looks good”

I’ve run a memory test which passed and also scanned the HDD and SDD with and both drives come back “Good”.

What should I look at next? ????

 

System details:

BIOS Version 1.23.0

AMD Ryzen 9 7900X 12-Core Processor

NVIDIA GeForce RTX 4080

CPU Speed 4700 MHz

HDD ST2000DM008-2UB102-(SO) 2000GB

SDD PC801 NVMe SK Hynix 1TB-(SO)

Memory 32768 (DDRS)

    Your BIOS version is 1.23.0; check Dell/Alienware support for newer BIOS updates.

    Sometimes BIOS updates fix stability issues, especially with newer CPU and GPU combos.

    Warning: Follow Dell’s instructions carefully when updating BIOS to avoid bricking your system.
