Windows 7: BSOD on boot - stop code 0X0000007F Dell Latitude Laptop

BSOD on boot - stop code 0X0000007F Dell Latitude Laptop

Hi:

Dell Latitude 6500 laptop running OEM Windows 7/32 SP1, fully patched and previously stable.
Rig will be 4 years old in a few months, so I suppose it could be impending hardware failure?

FWIW, drivers are UTD according to Dell site, but there is a BIOS update available (I hadn't updated it, as the rig had been very stable).


BSOD with stop code 0x0000007F.
Was able to reboot into Windows without incident immediately thereafter.

  • There was a recent patch to my security suite (KIS2013) within the past few days.
  • However, the rig had been rebooted several times since then without incident and the system was stable.
  • And I installed MS KB2840149 on 4/24 without incident, having uninstalled KB2823324 shortly after the Patch Tuesday debacle (even though I had NO problem with 2823324).
  • No other recent software or hardware changes.
  • KACE & encryption software have been installed for quite some time, and have caused no known issues.

SF Diagnostic Tool log & zipped mini-dump are attached (I think).

Please advise.

Much appreciated!

NOTE: This is NOT the system listed in my profile's "system specs". I have 3 different Windows 7 rigs. The one for which I am reporting this BSOD is the laptop.

Hello MoxieMomma.

The BSOD is caused by Kaspersky Antivirus, which made Intel(R) WiFi Link 5300 AGN driver blocked.

Uninstall Kaspersky using Kaspersky Removal Tool. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.
Download, install and update those, and then run full system scans with both of them, one by one.

Update Intel(R) WiFi Link 5300 AGN driver from https://downloadcenter.intel.com/def...me_downloadctr

Free up the startup. Windows does not need any other program to auto start with it, but the auto start programs often conflicts and causes various problems including BSODs.
  1. Click on the Start button
  2. Type “msconfig (without quotes), click the resulting link. It will open the System Configuration window.
  3. Select the “Startup” tab.
  4. Deselect all items other than the antivirus.
  5. Apply > OK
  6. Accept then restart.
Let us know the results.

Thank you, Arc, for your prompt and expert reply.

KIS driver:
It appears that the BSOD can be attributed to the recent KIS patch.
FWIW, I have been running KIS on this system for nearly 3 years.
Before undertaking the KIS uninstall > MSE install, etc, I think I might submit a ticket to KL Tech Support.

Wifi Driver:
I could well be wrong about this (as I am just a home user), but I was always instructed over the years with many OEM systems to obtain driver updates for OEM systems only from the computer manufacturer, not from the hardware component manufacturer?
IIRC the rationale is that the OEMs test the drivers and sometimes customize them for their platforms?
Is that no longer the case?
I just looked this morning on the Dell drivers and downloads page for my service tag and I **thought** I had the current Wifi driver.
I will look again.

Anyway, this looks as if it's going to be a time-consuming ordeal.
So, it may be a few days before I can report back with progress.

Thanks so much for your excellent help!
