PC suffers sudden restarts / power cutoffs under normal home load, but shop claims it passes synthetic tests (Kernel-Power Event ID 41)

RYZEN 75700G

System Summary & Problem:

​Issue: Sudden power cutoffs and instant reboots while using the desktop PC at home for regular tasks (opening apps, multi-tab browsing, light workloads). No Blue Screen of Death (BSOD), just direct loss of power.

​History: The PC worked completely fine in the exact same setup and wall outlet for months prior without any electrical or power issues.

​Diagnostic Logs Found:

​Windows Event Viewer: Multiple Kernel-Power Critical Errors (Event ID 41, Task Category 63) recorded on. These logs explicitly record unexpected hardware power loss during both home use and bench testing dates. I asked the shop about the kernel issues during the date the unit was in the shop and they didn't respond about it.

​Service Center / Repair Shop Diagnostics:

​Tests Passed on Bench:

​CPU/GPU stress test using OCCT 4.5.1 (run for 1h 49m) passed with no errors.

​Storage health evaluated via Partition Guru (zero bad sectors/tracks).​

OS reformatted, drivers reinstalled, and basic games/multitasking tested over 3 days. (As per shop )

​Shop's Stand: The shop issued a Technical Report stating no errors were observed on their bench. When confronted with the Kernel-Power logs, they claimed it didn't restart on their end and suggested contacting the local electricity provider to inspect home wiring.

Note: This unit is still under warranty.

What should I do? They keep on insisting there's no problem on it. I am rlly not a techy person. So your suggestions will be a big help.
