Safe next steps
- For 0x00000049 (PAGE_FAULT_WITH_INTERRUPTS_OFF), record the stop code, parameters, recent drivers, and whether Windows remains stable in Safe Mode.
- Use an official memory diagnostic only as evidence; this code alone does not prove that a RAM module is bad.
- Back up files before extended tests or system changes, especially if startup or storage is unstable.
After one step, repeat the original operation and record whether this same code returns. A different code needs a fresh interpretation.
