Random BSOD Ntoskrnl.exe +80640 or 71f00

[Marie78]

Hello all,
I am trying to fix the laptop of my mother, as it started to produce random BSOD, I tried with a fresh install of Win seven 64bits with no successes. I ran a memtest 86+ during almost 3 hours with no errors, and a Prime 95 stress test more than one hour and also no errors or bsod.

I attached the dm log.

Many thanks in advance for your help.

Welcome.

Remove Avast! and install MSE.

Microsoft Security Essentials is recommended from a strict BSOD perspective, compatibility & stability
compared to other antivirus or internet security software. It is free and lightweight:-

• Microsoft Security Essentials - Free Antivirus for Windows
• Malwarebytes: Removes malware including viruses, spyware, worms and trojans, plus it protects your computer
• http://www.sevenforums.com/system-security/206705-good-free-system-security-combination.html

   Warning

Do not start the free trial of Malware Bytes; remember to deselect that option when prompted.

Update these drivers to their latest. Specially the display drivers.
