BSOD very random ntoskrnl.exe

Hi to all

I have an error message BSOD from November.

It's very random and i don't know if it is an hardware or software (driver) problem.

In all cases is involved the file ntoskrnl.exe.

For now i send you the zip file as instructed.

S.O. Windows 7 64 bit Home Edition

Video Card GeForce 550 Ti Gtx.

Tell me if you want other information.

Thanks in advance

Kaspersky is contributing in your BSODs.

Code:

fffff880`0eb69aa8  fffff880`04d05ecdUnable to load image klif.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for klif.sys
*** ERROR: Module load completed but symbols could not be loaded for klif.sys
 klif+0x24ecd

Description here: Driver Reference Table - klif.sys

Uninstall Kaspersky using Kaspersky Removal Tool. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.
Download, install and update those, and then run full system scans with both of them, one by one.

The display driver is also failing there.

And it is the latest version. Try to roll it back to an earlier version that worked good there.

Daemon Tools, Alcohol 120% and Power Archiver Pro uses SCSI Pass Through Direct (SPTD), which is a well known BSOD causer. Uninstall Daemon Tools at first. Then download SPTD standalone installer from Disk-Tools.com, and execute the downloaded file as guided below :

• Double click to open it.
• Click this button only:
• 
• If it is grayed out, as in the picture, there is no more SPTD in your system, and you just close the window.

Free up the startup.

1. Click on the Start button
2. Type “msconfig (without quotes), click the resulting link. It will open the System Configuration window.
3. Select the “Startup” tab.
4. Deselect all items other than the antivirus.
5. Apply > OK
6. Accept then restart.

Let us know the results.

As you have noticed, I found three different contributors of the BSODs. When Kaspersky and SPTD is removed, it remains the display only.

As it is a branded desktop, and display is crashing, you first check the PSU. Is it supplying adequate power there or not.

Also, is the computer hot? Report us the heat of the computer after a couple of hours of your normal usage. Upload a screenshot of the summery tab of Speccy.

Take the two hardware tests I suggested earlier, too.

Hope we will be able to find out the reason behind the display crashes.

The CPU is hot, it is at a critical level of heat from which it may take an upward turn anytime.

Before suggesting anything, waiting for the other results.

That is why I suggested you to uninstall Kaspersky. Yes, it is Kaspersky that was causing the BSODs there.

No, Kaspersky was not conflicting with any other installed software or program; it was conflicting with the system. In some countable instances it happens. As a third party security program, its intention is to secure you. For that purpose, it will block things which are not safe to it. But things that are not safe to it are not necessarily unsafe, specially the OS elements like Ntfs.sys, fltmgr.sys, fileinfo.sys and tcpip.sys. If those are blocked, your HDD usage will be blocked all of a sudden ... your network access will be blocked all of a sudden. So it will result in a BSOD.

Kaspersky's intention was good, but it failed to discriminate between malicious and non malicious things properly .... blocked system resources unnecessarily, caused BSODs.

Hope it is clear now?
