Random BSOD ntkrnlpa.exe and sometimes win32k.sys

[JamesLens]

Hey guys, I have been randomly getting BSODs now for a while, usually a few a day while doing simple things like browsing the internet or reading a pdf.

I have uploaded the latest 5 minidumps as well as a system information file on the following link: https://skydrive.live.com/redir?resid=B4EBB68BC7BFC2DD!227

Any help greatly appreciated.

Thanks

Use this to upload all the files here...

 

[centaur78]

Also use this to update your system specs

 

[JamesLens]

Done, the files are attached to this post.

Thanks

I noticed that in addition to it crashing randomly during the day it always crashes during the first cold boot of the day as it logs into windows, as soon as the windows logo goes away a crash occurs. That is typically when win32k.sys is shown in bluescreenview in addition to the usual ntkrnlpa.exe

Also I reinstalled windows a few times before this as I remember this has been an ongoing issue, though not quite this bad. A few months ago I changed video card and its location in the motherboard and that seemed to fix things for a while but now it is happening again regardless of clean installation.

Thank you

Can you follow this tutorial: http://www.sevenforums.com/tutorials/105647-ram-test-memtest86.html

so we can rule out the memory being faulty

Thanks

 

[JamesLens]

Completed 8 passes of memtest, 0 errors.

Thanks

I performed some stress tests, results are as follows:

Furmark: With dynamics BG, Burn in, Xtreme Burn in and Post FX after 15 mins: 92 degrees Celcius.

I then wanted to run IntelBurnTest, but the TCase for my CPU is 71.4 degrees, while it was idling at 52 and 60 for one core, and the test required a differential of 20 so I decided not to do it.

Instead I ran Prime 95 on the Small FFT setting. The moment I started the stress test temperatures shot up to over 100 degrees Celcius!

Is this a possible reason for the BSODs?

Thank you

 

[JamesLens]

Cleaned out the CPU fan so the CPU now idles at 26-33 degrees celcius, which is a huge improvement. Tried running IntelBurnTest, temperatures now going to approximately 80, and at times still shooting up to 103 degrees celcius.

Hi James

There were 142 times the below entry in your logs starting from 11th April 2012 till the latest...

Event[34980]:
Log Name: System
Source: Microsoft-Windows-Kernel-Power
Date: 2012-08-22T03:43:43.596
Event ID: 89
Task: N/A
Level: Information
Opcode: Info
Keyword: N/A
User: S-1-5-18
User Name: NT AUTHORITY\SYSTEM
Computer: Morpheus
Description:
ACPI thermal zone ACPI\ThermalZone\THRM has been enumerated.
_PSV = 346K
_TC1 = 4
_TC2 = 3
_TSP = 6000ms
_AC0 = 346K
_AC1 = 0K
_AC2 = 0K
_AC3 = 0K
_AC4 = 0K
_AC5 = 0K
_AC6 = 0K
_AC7 = 0K
_AC8 = 0K
_AC9 = 0K
_CRT = 348K
_HOT = 0K
_PSL - see event data.

Thats in Kelvin ie ;

_PSV = Temperature to start passive cooling by throttling down CPU, etc. = 346K = 72.85 deg C
_AC0 = Temperatures at which to switch to the corresponding active cooling level. The lower the _ACx value, the higher the cooling power = 346K = 72.85 deg C
_CRT = Temperature to start critical shutdown (S5) = 348K = 74.85 deg C

Even though these are not very high...... is seems like the system shutdown at the critical temperature


Could you confirm if your system is shutting why using normally ???

 

[JamesLens]

My system does shut down when using normally, as in just when a browser and a few folders are open it can crash, nothing specific as far as I know sets off the BSODs.

 

[centaur78]

al right james

since you have cleaned your cpu ... let me know if it still bsod's... Keep an eye on the temps... and then if it BSOD not hang but BSOD's then upload the dmps.... i will have a look....

 

[JamesLens]

It already has BSOD'd after I cleaned the CPU, I attached the minidump for it.

I haven't used the computer since then as I haven't been home, but if it BSOD's again, which I'm sure it will, I'll attach another minidump.

 

[JamesLens]

Just had another one as expected

Uploaded this one too.

Thanks

 

[JamesLens]

And one more just now

 

[JamesLens]

Oh yes, today I had enabled Driver Verifier, could explain the frequency of BSODs.

Hi

Could you do a chdsk on the HDD ?

Whats PSU wattage ??

 

[JamesLens]

Performed full chkdsk (with error correction), event log attached. Seems to be ok though from what I can see.

PSU wattage is 550W

 

[centaur78]

Go to event viewer and save the system and application logs in .evtx format and upload here.. eg as shown

Sorry uploaded wrong file. I can't seem to upload it, it's 20MB and the max allowed is 8 MB.

Edit: Fixed. It's late, excuse me
