Error code BSOD triggered by unexpected store exception following PSU and case swap (may not be connected).
Error code BSOD triggered by unexpected store exception following PSU and case swap (may not be connected).
I’ve experienced frequent BSODs marked by the UNEXPECTED_STORE_EXCEPTION code. This began after I changed my PC case and power supply. The crashes appear randomly—every few days, while in use, such as gaming or browsing. They don’t happen when the system is idle. The machine usually powers down gently, never shuts off completely.
Specs: CPU – Intel i9-12900K (declocked, XMP disabled); GPU – NVIDIA RTX 4090; RAM – 64GB (2x32GB); Storage – Samsung 990 Pro 2TB NVMe (non-RAID); PSU – Corsair SF1000L Platinum; Board – ASUS ROG Maximus Z790 Hero (latest BIOS); OS – Windows 11 Pro 64-bit. Cooling stays low under load and idle.
Changes I made: swapped case, tried reinstalling Windows twice, ran MemTest, used Samsung Magician and CrystalDiskInfo, verified CPU placement, updated drivers and BIOS, kept no overclocking. All tests passed.
What I’ve done: reset and reinstalled OS twice; performed system checks; ensured proper hardware seating.
Behavior: Occurs intermittently, roughly every 2–4 days, under load or light tasks. Never during full shutdown. System stays on sleep mode, never fully off.
Possible causes: Could be related to power supply stability despite its quality? Fast startup settings might influence it? I’m looking for further diagnostics. Any leads?
It appears there might be a memory-related problem, especially in systems with high RAM where a drive fails only after being accessed or written. Consider restarting in advanced startup mode (hold Shift during reboot) and using automatic repair. The issue could stem from Windows corruption triggered by a feature activation. Let me know if you notice it more often on particular games or websites.
