I'm getting frequent BSODs on my custom-built desktop, always with the same stop code related to memory management, but my RAM passes multiple rounds of MemTest86. I've updated all my drivers, checked for overheating, and reseated the components. The crashes seem random but often occur under moderate load, not necessarily heavy gaming. For those who have solved similar elusive BSOD issues, what was the final culprit, and what diagnostic steps beyond basic hardware tests finally pinpointed the problem, whether it was a driver conflict, faulty motherboard, or something else entirely?
Try swapping RAM slots and testing sticks individually. A single bad memory slot on the motherboard can cause memory-management BSODs even when the RAM checks out in MemTest86.
When I hit this, enabling Driver Verifier and stressing a few drivers pointed to a conflict (often graphics or antivirus). Disable or update the culprit driver, or roll back to a known-good version and test stability.
BIOS/overclocking can masquerade as memory issues. Reset the BIOS to defaults, disable XMP/DOCP, and see if stability improves. If possible, update the motherboard BIOS and make sure your RAM is on the vendor’s QVL list.
Power supply quality can show up as memory instability under load. Check the 12V rails in BIOS or with a PSU tester, and consider trying a known-good PSU if you have one available, to rule that out.
Comprehensive diagnostic path: after MemTest86, run Windows Memory Diagnostics for a second pass, collect crash dumps, and analyze with tools like WinDbg or BlueScreenView. Test each RAM module in each slot, and run a GPU/CPU stress test to see if the crash reappears under combined load; check for overheating as well.
If you want, share your system details (motherboard model, RAM model, BIOS version, OS, GPU) and any dump files you have, and I can help map out a precise step-by-step plan.
