Windows 7: BSOD looking for analysis

BSOD looking for analysis

I am having freezes, or freezes and restarts mostly. May be hardware, but I had this BSOD and am interested as to the cause to see if any connection. I'll likely be posting for help in the hardware section soon as well, but wanted to see what the BSOD cause was 1st. Some history:

Last Sat., early Sun. was the 1st sign of any problem. Was watching a full screen Youtube video when my sound stopped, screen went black, and the PC froze. It stayed on, no response to anything, no Numlock light on keyboard. After it became obvious it wouldn't blue screen, or restart, did a hard power off.

Upon restarting, I noticed the ASUS splash screen and option to enter Express Gate showed up. These were disabled in BIOS since day one. Turns out my BIOS was reset, cpu and ram settings, etc. reset them and off I went.

Since then, I have had many freezes, either just staying frozen requiring a hard power off, or a freeze followed by a restart. This results in a kernal power event 41 (63), basically saying it didn't shut down properly. I did get a bugcheck 127 (07f) at one pint, but I am getting all zeros since.

Last Sun./early mon. I ran Memtest+ for 8 hours, 17 passes, no errors. I swapped out my GPU for a spare. The BSOD is with the replacement GPU and the driver windows found, so be aware if it points towards GPU driver, it may have been caused by that.

I had updated my Nvidia driver days before, so I restored to an Acronis image from the weekend before. I surfed 4 hours or so last night in Safe Mode with Networking with no issue (maybe coincidence). Booted to a clean start and started a Malwarebytes scan before going to bed. Awoke to a frozen PC, so the clean start did not prevent the freeze.

So, to wrap up, Memtest+ results showed nothing. Replacement GPU made no difference. Restored image from the week before made no difference. Safe Mode with Networking inconclusive, as it did work last night. Clean start no help.

I had cleared my events as I wanted to make sure any new events were obvious. But all were kernel power events. Appreciate any analysis of this one BSOD, so I can see what caused it, and if it has any connection. Also including pictures of the Blue screens, one from 9/26 that is for the attached dump, and one from 9/28 where the dump was not saved for some reason.

I would suggest uninstalling CoreTemp and see if the BSOD returns.

Thanks guys, suspect the BSOD was an abberation, and not connected to my other issues. Will leave it as is, and see if I get a repeat BSOD. Just reset BIOS by removing the CMOS battery. Going to see how ai get on in a regular windows environment after my Acronis image restores. A Guy

You can also see if your chipset driver is the newer one along with current BIOS. P7P55D - Motherboards - ASUS

It is possible the PCIex16 slot is dodgy, try using the other one.

Hello Bill, here is my $0.02

Please reduce the items that run at start up. You basically only need your anti virus to run at start up, all other programs are not necessary and can be removed from the start up list.
Check this tutorial to see how to add or remove start up items.

----------

Code:
Start Menu\Programs\avast! Free Antivirus    Public:Start Menu\Programs\ avast! Free Antivirus    Public
Start Menu\Programs\Avira    Public:Start Menu\Programs\Avira    Public
Start Menu\Programs\Avira\Avira Desktop    Public:Start Menu\Programs\Avira\Avira Desktop    Public
warning   Warning
are you aware that having multiple AV's can cause problems for your PC?
Having multiple AV's that all offer real-time protection will cause them to interfere with each other, and that will result in the opposite of what you are trying to achieve.
Problems that can be caused include a slow computer, false positives, conflict of programs, causing them to stop working, freeze or use way to much RAM, and last and most important, more vulnerability to infections.
Read this for more info Multiple AV's is a bad idea.

----------

I'd advice you to remove one of them, first either via Control Panel > Uninstall a Program or by using Revo Uninstaller Free, and then by using the specialized removal utility from this list.

Use !analyze -v to get detailed debugging information.

Could not read faulting driver name
Probably caused by : win32k.sys ( win32k!NtUserGetProp+3d )

Followup: MachineOwner
---------
Usual cause: Faulty RAM, faulty hardware, faulty system service, interfering AV.
More info Bug check 0x50.

----------

Both BSoD's point to a Windows driver (win32K.sys and fltmgr.sys), and those shouldn't fail on their own. Since you have two AV's installed, I'd say that that's the place to start

----------

If the BSoD's continue after this, please scan the system with SFC;
Please use the SFC /SCANNOW command as displayed in option two of this tutorial.
  1. Click on the .
  2. Open an elevated command prompt.
  3. Type "SFC /SCANNOW" without the quotations.
  4. Let SFC do it's thing, and then prompted to, restart.

    If SFC found and repaired anything, please do the following:
  5. When restarted, open an elevated command prompt.
  6. Type (or copy) the following, this will create a .txt file on your desktop;
    findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt"
  7. In your next reply, please attach this file using the method displayed in this tutorial.
----------

If SFC turns out clean, please enable Driver Verifier to pinpoint the cause;
Please follow this;

Why Driver Verifier:
It puts a stress on the drivers, and so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

warning   Warning
Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

Good luck and keep us posted,

Thanks Stefan, I should have marked this solved. I removed the CMOS battery and reset BIOS, and all is well

I don't have 2 AV installed with real time protection. The Avira is for on demand scanning only, installed with the guard off.

I do want multiple items starting with windows, as I use all those My PC starts in 46 seconds, so time is not an issue. I'm sorry I wasted your time, but truly appreciate the analysis

Understandable. Most of the time we have less techy people post here with BSoD troubles, and usually they don't even have a clue about start up items.
But damn, 46 seconds is fast!

No need to be sorry my friend. You didn't waste my time at all. As I said, it was my $0.02 and I kind of had the idea that you've already solved it
