BSOD and non-BSOD crashes

ekpuz · 22 May 2016

I've been getting random system freezes and crashes, usually without a BSOD but occasionally with "UNEXPECTED_STORE_EXCEPTION" or "CRITICAL_PROCESS_DIED". When it is not the BSOD I can usually see any open windows but otherwise system is completely unresponsive. No mouse or keyboard input seems to have any impact (including CTRL-ALT-DEL). Only option is to power cycle. Sometimes I come to my computer and it has attempted to reboot but with some sort of "reboot and select proper boot device" message. Power cycling will usually allow it to reboot properly (although it can take a while).

Thanks in advance for your help.

The crash dumps are not very latest other than that one of 10th May. But they all are pointing to Cisco Anyconnect.

Code:

BugCheck C5, {760e0017, 2, 0, fffff800976a5840}

*** WARNING: Unable to verify timestamp for acsock64.sys

With two different Kaspersky drivers flagged.

I see Cisco is disabled there.

Code:

Cisco AnyConnect Secure Mobility Client Virtual Miniport Adapter for Windows x64 #2    ROOT\NET\0000    This device is disabled.

But that does not prevent Cisco from running in the background.

Code:

Cisco AnyConnect Secure Mobility Agent    vpnagent    Running    Auto    Own Process    "c:\program files (x86)\cisco\cisco anyconnect secure mobility client\vpnagent.exe"    Normal    LocalSystem    0

If you disabled Cisco on intention, please uninstall it?
If the system disabled it, better you uninstall it.

See the situation without Cisco. Let us know how it goes.
