STOP 0x000000C1 : SPECIAL_POOL_DETECTED_MEMORY_CORRUPTION

STOP Errors are usually the result of a hardware malfunction or device driver issue. It is also possible to receive a Blue Screen Error due to bad system memory, malfunctioning power supply, components overheating, or hardware overclocked beyond its specification.
