Windows 7: Many BSOD's involving ntoskrnl.exe (nt+0x75C40)

CrazyDutchwoman · 14 Mar 2013

I have to admit it is scary to start a thread here. I did read the instructions and hope I did everything correct.

The bsod have been going on for months now.

I am using a windows 7 PC on 64 bit
Intel Core i5 processor. (I've added all the info in my profile) but just to be sure I will add it here too.
Memory:2,40 Ghz and installed memory only 4 GB
NVIDIA Geforce310M

What I did was download whocrashed so that was why I noticed most of the time it has to do with ntoskrnl.exe. Appears to be memory.

Thanks in advance for trying to help me out.

It looks like your problem is coming from avast!:

Please remove Avast! using the Avast! removal tooland replace it with a combination of MSE and Mbam.

Tip: When installing Mbam be sure to uncheck the box offering t start a free trial.

Wow That is unexpected. Thanks for helping me out.I will do what you suggest and see if the bsod's stop.
Will post if they do or if they don't :) Thanks again!

Would love to learn to decipher these myself and I see there is a thread here where you can start understanding more.

Looking forward to you results.

CrazyDutchwoman · 14 Mar 2013

ETA: That is weird. I did what you said with all the handy links that was easy, and I made sure not to enable the trial from MAM but now when I look it says 13 days left -trial.

That is rather odd, try uninstalling and re-installing it see if that helps.

Hi. Last night I had another crash.

For your information. I had removed the Mbam and not yet rebooted to re install when the crash happened.

I have this info for you but if you want me to add another zip file I can do that.

On Fri 3/15/2013 9:48:32 PM GMT your computer crashed
crash dump file: C:\windows\Minidump\031513-26114-01.dmp
This was probably caused by the following module: ntoskrnl.exe (nt+0x75C40)
Bugcheck code: 0x50 (0xFFFFBA8008905840, 0x0, 0xFFFFF80003095C36, 0x7)
Error: PAGE_FAULT_IN_NONPAGED_AREA
file path: C:\windows\system32\ntoskrnl.exe
product: Microsoft® Windows® Operating System
company: Microsoft Corporation
description: NT Kernel & System
Bug check description: This indicates that invalid system memory has been referenced.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem.
The crash took place in the Windows kernel. Possibly this problem is caused by another driver which cannot be identified at this time.

I wanted to send the dmp add it to a zip file but no permission.

Thanks in advance.

nvm I decided to do it all again so I made a new zip file

The particular BSOD you got is a 0x50:

BugCheck A, {6800060b92a, 2, 0, fffff80002eb5ceb}

Probably caused by : memory_corruption ( nt!MiMapPageInHyperSpaceWorker+1b )

Followup: MachineOwner
---------

Code:

Usual causes: Defective hardware (particularly memory - but not just RAM), Faulty system service, Antivirus,  Device driver, NTFS corruption, BIOS

So please run the following commands:

Quote:

SFC.EXE /SCANNOW
Go to Start and type in "cmd.exe" (without the quotes)
At the top of the search box, right click on the cmd.exe and select "Run as adminstrator"
In the black window that opens, type "SFC.EXE /SCANNOW" (without the quotes) and press Enter.
Let the program run and post back what it says when it's done.

then from the same command prompt run this command

Code:

chkdsk /f /r

the second command will ask you to reboot please do.

once that is completed please check the system manufacturers website for updates to your bios it is rather old:

Code:

BIOS Version/Date    American Megatrends Inc. E168AIMS.10A, 19-7-2010

and last please run memtest86+ for atlast 8 passes to check for problems with ram: RAM - Test with Memtest86+

Tip: Do this overnight it can take quite some time.
