Windows 7: Event 41 Kernel-Power random crashes

Event 41 Kernel-Power random crashes

I have recently replaced my old laptop's HDD and ever since I installed windows 7 64bit I have been getting some random system restarts. This happens with no blue screen whatsoever, it's like the power suddently went down. These system restarts have happened while browsing the internet, using a few programs (like visual studio or unity) or sometimes even when windows is booting (at the 'Windows is starting up' splash screen)

Taking a look at my event viewer I see a Event 41 Kernel-Power critical error at the time of the crash. This may or may not be relevant but I also see another entry "Broadcom NetLink(TM) Gigabit Ethernet has initialized sucessfully" at the exact same timestamp as the kernel error. I have tried updating drivers for this device with no avail.

Below is a DMLog attached

Thanks for your time

It seems to do this more often when windows is booting now. I'm running out of ideas at this point :/

There are no dump files in your logs.
  1. Open Advanced System Settings
  2. Click on Settings in Startup & Recovery
  3. Make sure both boxes indicated below are checked
  4. In the dropdown box ensure you're set to record Small Memory Dumps

Done. So should I wait for another crash before submitting another DM log file?

I have not experienced another crash while using Windows, however it has crashed again while starting up. This is becomming more often now. Same error as before (kernel 41) and no minidump was created. :/

From the single dump this one looks pretty straight forward (famous last words).

 ESET

ESET is causing the problem.
Code:
fffff880`08752ec8  fffff880`03f247f2Unable to load image ehdrv.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for ehdrv.sys
*** ERROR: Module load completed but symbols could not be loaded for ehdrv.sys
 ehdrv+0x1c7f2
Uninstall ESET and install MS Security Essentials and MalwareBytes.

Note   Note
Make sure you uncheck the 'Enable Free Trial' box when installing.





 DaemonTools

Uninstall Daemon Tools, a proven cause of BSODs.

1. Uninstall Daemon Tools.
2. Download the SPTD standalone installer and perform the following steps.
3. Double click the executable to open it.
4. Click the button shown below.



information   Information
If the button it is grayed out as shown in the image, there is no more SPTD installation on your system and you can close the window.

Done. It's a shame to let ESET go, it looked like a good antivirus.

Will let you know if blue screens persist.
