HI. Im sorry if this thread seems like a double post but let me explain my problem. Im have World of Warcraft installed on my PC (yes they got me). As probably a lot people know this is online game that have patches applied to it. My PC worked fine up until recent patch. I have several characters in this game and it loads up fine with any lower level character BUT the high level character coasting system to crash with following BSOD: DRIVER_IRQL_NOT_LESS_OR_EQUAL STOP: 0x000000D1(0x0000000E, 0x00000002, 0x00000000, 0x0000000E) I know that it means but I don’t know which device is faulty and how to fix it. Yes I did search the site for this topic and none of the findings answered my question.
