Windows 7: BSOD occasionally when browsing, sometimes on startup

BSOD occasionally when browsing, sometimes on startup

I'm getting a BSOD when browsing (IE9) mainly if on flash sites, but sometimes standard websites. Occasionally it will also crash when the Windows 7 logon screen comes up and reboots itself. Never crashes if left on for long periods and not using (I use it to stream media via DLNA).

Any help greatly appreciated. Zip file attached. Using Windows 7 Ultimate 64 bit.

Many thanks

Steve

Hello steviep43.
Code:
fffff880`081390e8  fffff880`07805f61Unable to load image \??\C:\Windows\system32\drivers\aswMonFlt.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for aswMonFlt.sys
*** ERROR: Module load completed but symbols could not be loaded for aswMonFlt.sys
 aswMonFlt+0x5f61
Uninstall Avast using Avast Uninstall Utility. 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.

Thanks. I used to use AVG but thought it might be the problem so went for Avast instead. I'll give Windows Security a try in that case. Is that the same error that's coming up in all the dump files?

I have checked the latest ones only. And, as it is the concurrent issue, you mist to fix it at first, and then, if the problem persists, we will search for more causes, for sure.

I uninstalled Avast and installed Windows Essentials. Interestingly when it did a full scan it found some threats Avast didn't. I can now seem to browse sites with no BSOD however on the first reboot it BSOD'd on the login screen immediately and rebooted itself. This has not happened since so I'm hoping it was a one off relating to the removal of Avast. Early days so I will keep you posted.

Many many thanks for your assistance

Your crash dumps are not showing any finite probable cause. In such a situation, it is better to enable Driver Verifier to monitor the drivers.
Driver Verifier - Enable and Disable
Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

information   Information
Why Driver Verifier:
It puts a stress on the drivers, ans so it makes the unstable drivers crash. Hopefully the driver that crashes is recorded in the memory dump.

How Can we know that DV is enabled:
It will make the system bit of slow, laggy.

warning   Warning
Before enabling DV, make it sure that you have earlier System restore points made in your computer. You can check it easily by using CCleaner looking at Tools > System Restore.

If there is no points, make a System Restore Point manually before enabling DV.

Tip   Tip

Let us know the results, with the subsequent crash dumps, if any.

I ran it for the last two days and typically got no crashes Any other suggestions? Should I keep it running for longer?

No, not at all. You have done enough with it.

Disable verifier. Use the computer normally. If it crashes again, let us see.
