[HELP] Persistent MEMORY_MANAGEMENT (0x1A) and Fatal Errors on i5-14400F / B760 Gaming X AX (Rev 1.2)

Hi everyone,

I’ve been battling constant BSODs and game crashes for a few days now and I’m at my wits' end. I’m looking for advice on whether this looks like a faulty CPU (degradation), RAM issues, or just a corrupted OS.

My Specs:

  • CPU: Intel Core i5-14400F
  • MOBO: Gigabyte B760 GAMING X AX (Revision 1.2)
  • RAM: 32GB DDR5 (Passed MemTest86 with 0 errors)
  • GPU: AMD Radeon rx 9070 xt (Running on stock settings)
  • PSU: Gigabyte 850W Gold+
  • OS: Windows 11

The Symptoms:

  • Constant MEMORY_MANAGEMENT (0x1A) Blue Screens.
  • Occasional REGISTRY_ERROR and SYSTEM_SERVICE_EXCEPTION (once pointing to FACEIT_AC.sys).
  • Games crash with a "Fatal Error" message shortly after launching.
  • Strange "Access Denied" errors in CMD even when running as Administrator.
  • Temperatures are fine: CPU and GPU temps are well within normal ranges under load, so overheating is not the issue.

Important Context: These issues have been happening almost since I got the computer, but only under heavy load. I can play less demanding games like CS2 or League of Legends for hours without any crashes. The problems only start when I run more demanding titles (like Red Dead Redemption 2 / "Far Far West").

What I’ve done so far:

  1. BIOS Update: Successfully updated to version F15. Used gigabyte app because standard Q-Flash gave "Can't Read File" errors.
  2. BIOS Settings: Currently running on Intel Default Settings. XMP is Disabled, Re-Size BAR is Disabled.
  3. Storage: Ran chkdsk /f /r from Recovery Mode. 0 bad sectors found.
  4. OS Repair: Ran sfc /scannow and DISM – both reported the system is healthy.
  5. Memory: Ran a full MemTest86 – no errors found.

My question: Before I pull the trigger on a clean Windows re-install (format), does this sound like a hardware failure (CPU/Memory Controller degradation) or is it possible that the initial instability just nuked my Windows registry beyond repair?

Any help would be appreciated!
