Bug check 0x000000C1 (SPECIAL_POOL_DETECTED_MEMORY_CORRUPTION) means a driver wrote past the end of its allocated memory in the special pool. This is caught by Windows special pool allocator (often enabled via Driver Verifier). The minidump directly identifies the offending driver. Fixes:
- The minidump will name the faulting driver — update or remove it,
- If you enabled Driver Verifier to find this: great, you found the bad driver, now disable Verifier (verifier /reset) and reboot,
- If this appeared without Driver Verifier: a random driver corruption was caught — update all drivers,
- Run memtest86 to ensure RAM is not contributing to the corruption.
