Windows 7: Unattended Bluescreens

Unattended Bluescreens

Hopefully someone will be able to help me as I am coming unravelled trying to fix this problem.

I built this PC myself and it has run without issue for months, up until a week ago. At that time I started receiving random BSODs although only when the computer was not being used actively (i.e. I'm not at the keyboard). I can play games for hours or browse without issue, but if I leave there is a good chance of a bluescreen when I get back.

Most of the bluescreens have been MEMORY_MANAGEMENT, although there have been a few PFN_LIST_CORRUPT as well as my personal favourite, IRQL_NOT_LESS_OR_EQUAL also making a guest appearance.

I have run Memtest overnight (10+ passes) with 0 errors, as bad RAM was my first suspicion. I have run extended tests on both of my hard drives using SeaTools and neither one had any errors (or any SMART warnings).

If anyone could take a look at the dumps and give any further advice I would appreciate it, since I am close to being out of ideas.

Thanks.

I have removed and uninstalled Avast using the linked uninstaller.

MSE is now installed and scanning.

Windows Firewall is enabled (I was using Comodo).

As per my post, I have already run Memtest86 overnight for 10 passes with 0 errors a couple of days ago, however I will do so again tonight.

Comodo has been uninstalled.

A scan with SAS found a few tracking cookies but nothing else.

Memtest ran overnight for 15 complete passes with 0 errors.

I bluescreened twice again yesterday, MEMORY_MANAGEMENT and then PFN_LIST_CORRUPT. Those minidumps are attached.

Sorry for the late response.

I swept away the old Nvidia driver and installed the latest.

I installed the latest DirectX redistributable and it did update several files.

sfc /scannow found no integrity violations.

OCCT found no errors on my video card, either on the video RAM or the GPU.

Prime95 ran for over 3 hours with no errors on the Small FFTs test (CPU stress).

I have actually not bluescreened in several days, ever since I updated DirectX on Sunday. Perhaps this was the issue, that some of my DirectX files were corrupted in some way and caused the problem?

I'll post back should another bluescreen occur. Thanks for the help so far!

Another bluescreen today, this time SYSTEM_SERVICE_EXCEPTION.

Dump is attached.

Correct me if I'm wrong, but the indicated file ladfBakerRamd64.sys would seem to indicate my Logitech G930 headset software.

Perhaps this is the problem?

Yes it is.

So update the software\driver,is better though to completely unplug it and uninstall software\driver for testing purposes.

Also,

Download\install\update and full scan with SUPERAntiSpyware.com - Downloading File

Download\install\update and full scan with Malwarebytes : Malwarebytes Anti-Malware is a free download that removes viruses and malware from your computer

Finish with above steps and post back with any results.
