Desktop Pc Randomly Restarts When Not Under Stress

Hi

I have a desktop computer that keeps randomly restarting - it happens when not under stress and can be within minutes of turning on. I've tried running chkdsk /f/r and turning off the auto restart function to catch the error, but the last time it happened the computer just froze with no blue screen. The PC is a custom build from overclockers and is about a year old, the power cable seems fine and is connected okay - it doesn't get used for downloading or gaming as it's our "office PC" that we use solely for business admin/video editing in our home.

Device specs - running Windows 11 pro
Device name DESKTOP-V5M8CVF
Processor AMD Ryzen 7 5800X 8-Core Processor 3.80 GHz
Installed RAM 32.0 GB
Device ID EDFE179C-C1D6-48CA-9484-329C2BE660AE
Product ID 00330-73745-00003-AAOEM
System type 64-bit operating system, x64-based processor
Pen and touch No pen or touch input is available for this display

Can anyone give me ideas on how to solve this problem? please let me know if you need any other information or logs etc.

Thank you (sorry if it's not in the right forum!)
