irregular BSOD on older Dell Laptop. error 0x0000009f and 0x0000001a

Hi guys,

Dell Studio Laptop
Windows 7 64bit
4Gb Ram
Intel Core 2 Duo

An irregular BSOD, about once a month, always caused by ntoskrnl.exe - often when hibernating, but sometimes in the middle of something.


Kept windows up-to-date as far as I know!

Attached is the SF report.

Any suggestions on how to fix much appreciated!

Hello timsparks, Welcome to SF

First off if your OCing in anyway stop, return everything to stock settings for the purposes of testing

If you havent already, fill in your system specs so we know what we are dealing with
System Info - See Your System Specs

Make sure you have read the guide on asking for help with BSOD so you know what we need
And if necessary set your machine to create minidumps (Method 2 Step 2 is easiest IMO)
Dump Files - Configure Windows to Create on BSOD

Run some scans to check against virus or infection
Anti-rootkit utility TDSSKiller
Windows Defender Offline

Run some basic hardware tests
RAM - Test with Memtest86+
Disk Check (windows based check)
Hard Drive Diagnostic Procedure (bootable disk check)

Nothing conclusive in the dump files i would start with the virus checks and some hardware tests see how you get on
What is the keytweak program you have installed ?

Hi Pauly,
Thanks for the reply.

Have put my system specs up, and had already been through the BSOD instructions. Attached file (in previous post) has the dumps and system info.

Will do some system scans now.

The KeyTweak program is a relic from when I was trying to re-map some of the irritating buttons that Dell put on the laptop (volume control) but to no avail. I've just uninstalled it...
