So recently I was experience a blue screen with the error code of SYSTEM_SERVICE_EXCEPTION. Today I turned on my PC expecting that same stop, but instead I've come to notice it's changed to IRQL_GT_ZERO_AT_SYSTEM_SERVICE. I thought there was a corrupt Windows driver from my research of SYTEM_SERVICE_EXCEPTION, but now I'm thinking it may be corrupt RAM, or the driver. I don't think it could be bad RAM, because I've had this PC since the summer, and had no issues. Anyone got anything?
