🧰 Diagnostic & Repair – Ryzen 3700X System

Service Summary:

Investigated and resolved intermittent boot loop and login issues

Identified root cause as unstable memory configuration (mixed RAM kits with XMP enabled)

Disabled XMP to restore long-term system stability

Performed full diagnostic testing:

• • ✅ 4x passes of MemTest86 (16GB and 32GB configurations)

  • ✅ 3+ hours of AIDA64 stress testing (no faults found)
    
    Updated Samsung NVMe firmware and installed latest NVMe drive
    
    Ran full Samsung Magician SMART diagnostic (passed)
    
    Repaired Windows file system and image using SFC and DISM
    Resolved Windows Hello PIN login issue by clearing and resetting credential subsystem
    Investigated and explained boot-time scan linked to a legacy Linux volume (non-impacting)

Result:
System now boots cleanly, performs reliably, and shows no signs of instability. XMP remains disabled to ensure consistent operation with existing memory configuration. No further issues detected.

Note- PC could possibly use a re-build to remove significant dust which could pose a problem in the future, or potentially even replace the fans and heatsync, as they can be very fiddly to clean properly.
