Blue Screen of Death (BSOD): IRQL_GT_ZERO_AT_SYSTEM_SERVICE Errors Explained

The Blue Screen of Death (BSOD) is a dreaded occurrence for Windows users. When it appears, it’s often accompanied by a cryptic error message that can leave even the most tech-savvy individuals scratching their heads. One such error that has puzzled many users is the “IRQL_GT_ZERO_AT_SYSTEM_SERVICE” blue screen of death.

What is IRQL_GT_ZERO_AT_SYSTEM_SERVICE?

IRQL_GT_ZERO_AT_SYSTEM_SERVICE is a type of Blue Screen of Death error that occurs when the kernel attempts to access a system service while the IRQL (Interrupt Request Level) is greater than zero. IRQL is a measure of the priority level of an interrupt, with zero indicating a normal, non-priority level.

When the IRQL is set to a value greater than zero, it means that the system is in a high-priority state, and any attempts to access a system service from this state can lead to a BSOD. The “IRQL_GT_ZERO_AT_SYSTEM_SERVICE” error indicates that the system has tried to access a system service from a high-priority state, which is not allowed.
