Hi Noémi Kouassi,
Thank you for posting on Microsoft Q&A forum and providing the crash dump details. I understand how disruptive and frustrating it is to experience repeated blue screen crashes, especially after upgrading hardware and running multiple diagnostic tests.
After reviewing the dump, the system is hitting an UNEXPECTED_STORE_EXCEPTION (0x154). In simple terms, Windows is crashing while handling memory that’s being written back to the drive. This usually points to a low‑level stability issue rather than a normal software or application problem.
To help narrow down the root cause, I recommend the following steps, in order:
Step 1: Temporarily run the system at default BIOS settings
Even when memory passes diagnostic tools, marginal instability can show up under real Windows workloads (memory compression and paging in particular). Please temporarily:
- Disable XMP/EXPO memory profiles and run the RAM at default speeds
- Disable any CPU undervolting, curve optimizer or overclocking features
This is only for testing and helps confirm whether memory timing or the CPU’s memory controller is contributing to the crashes.
Step 2: Test the system in Safe Mode
Safe Mode starts Windows with only basic Microsoft drivers and disables most third‑party software and background services.
- Hold Shift on your keyboard and click Restart from the Windows Start menu
- When the recovery screen appears, select: Troubleshoot > Advanced options > Startup Settings > Restart
- After the system restarts, you’ll see a list of options
- Press 4 (or F4) for Safe Mode, or 5 (or F5) for Safe Mode with Networking
If the system is stable in Safe Mode, it strongly suggests a third‑party driver or background tool (for example, antivirus, disk utilities, or encryption software) is involved.
If the system still crashes in Safe Mode, that points more toward a hardware‑level or firmware issue (memory, SSD firmware, or system stability).
Step 3: Check and update SSD firmware
The crash occurred during a disk write operation, so storage firmware is important to rule out. Please identify the model of your system SSD and check for firmware updates using the manufacturer’s official tool. These updates don’t usually come through Windows Update, but outdated firmware can cause crashes under heavy or sustained disk activity.
Step 4: Temporarily disable or remove third‑party disk or security software
If you’re running any third‑party antivirus, disk encryption, or storage optimization tools, please temporarily disable or uninstall them for testing. These types of tools operate very close to Windows’ storage and memory subsystems and can cause crashes without obvious error messages.
*Disclaimer: Temporarily turn off antivirus protection. However, keep in mind that if you do so, your device may be vulnerable to threats. So please turn it on immediately once issue fixed.
After completing these steps, please let me know:
- Whether the system becomes more stable
- If crashes seem to happen during idle time, heavy disk usage or after sleep/wake
Based on the results, we can safely narrow this down and decide the best next steps.
