Windows 7: BSOD in any browser. Memory Management. Driver Issue

BSOD in any browser. Memory Management. Driver Issue

I was getting lots of BSODs and THEN I started updating drivers. Seemed to get better, then got much worse. Please help to tell me which driver(s) are causing my issue. Note I was also getting a BSOD for another reason that escapes me right now - hopefully in one of the many crash logs.

I NEVER have been able to install SP1 on this machine. When I complained to HP when it was still under warranty, they said I did not need it. I have many many items from HP. NO MORE. This machine has been plagued with issues since I got it and their version of tech support is a joke. HP replaced the MB under warranty.

See attachment.

Thanks in advance for any help.

BugCheck 1A, {41790, fffffa80041a9810, ffff, 0}

Probably caused by : win32k.sys ( win32k!FreeView+a2 )
The first parameter indicates that a page table page has become corrupt, the second parameter, and since this is a x64 operating system, points to the PFN of the corrupt page table page.

Other good references are: The Basics:Bugchecks Explained: PFN_LIST_CORRUPT and CodeMachine - Article - Catalog of key Windows kernel data structures

Run Driver Verifier to scan for any corrupted drivers which may be causing problems, this program works by running various stress tests on drivers, in order to produce a BSOD which will locate the driver; run for least 24 hours:

How to fix if it is win32k.sys

Assuming it is Probably caused by : win32k.sys , how do I fix it? Can I just copy over that file with a good copy? If so, which one is it? Searching for it I find lots of them.

Have you followed any of my advice?

win32k.sys is part of the Windows subsystem, it's not the problem here.

Was unable to boot the drive so I couldn't run anything (see above).

Some more info. I have 2 hard drives with the HP win 7 premium on one and a microsoft win 7 premium on the other. They both experience the BSOD. We have been working through the worst one (on a SSD) which is the microsoft version. That is the one that stopped working. Attempted Startup repair and got an application error. Attempted a restore (recent restore disappeared). Did a SFC/Scannow. It then did a boatload of updates.

Thanks, will run Driver Verifier now.

You may have to use Command Prompt at Startup to turn on Driver Verifier, and then attempt to boot the computer. Otherwise, I would suggest following this guide - Troubleshooting Windows 7 Failure to Boot

One step forward, 2 steps back......

I connected through VPN and was able to run ESOP antivirus scan. Found 51 issues that were resolved over 2 operating systems and 3 drives (took about 13 hours to run).

When I started verifier it crashed before it fully booted. Then would no longer boot - got BSOD. Tried to restore, got an error and would not. It eventually was able to boot (in safe mode). Hopefully attachment will help. Thanks.

Could not do a repair. Did run SFC/scannow. It said it found corrupt files but was unable to fix some of them. Log file attached if that helps. Now that I think about it, before I did this same thing, I never got a system restore to work.
