BSOD - Twice in a day, DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)

josephjames19 · 30 Aug 2016

Have a user who experienced a couple BSODs in the same day, looking to preemptively identify the problem before it might get worse or interrupt work.

User is on a Dell Latitude E7450 running Win7 Pro 64-bit SP1. I've encountered a few driver issues with these laptops in the past, but am not well versed in identifying the driver creating the issue by using crash logs. Hoping you kind folks can help me out once more :)

Thanks very much in advance for any assistance!

It looks like this driver, WebExaminer64.sys, seems to cause issues. Unfortunately I am not aware as to what this driver is related to. My guess is a security program based on this information

Code:

3: kd> lmvm WebExaminer64
Browse full module list
start             end                 module name
fffff880`08d46000 fffff880`08d52000   WebExaminer64 T (no symbols)           
    Loaded symbol image file: WebExaminer64.sys
    Image path: \??\C:\Windows\system32\Drivers\WebExaminer64.sys
    Image name: WebExaminer64.sys

Ah, that looks to be a driver associated with our Vipre Antivirus software. Will look into which service is using this.

Thanks for the quick followup!
