Windows 7: BSODs and loss of internet connection upon restart

BSODs and loss of internet connection upon restart

Hi,

My computer is relatively recent only being bought back around Feb/March. For the past month the machine has been crashing and when I log back in I need to restart my router in order to get my internet connection back. The strange thing is that other computers connected to the same router also lose their connection shortly after the BSOD on my machine (both machines have wired connections). I am using the same OEM copy of Win 7 Professional 64 bit that was installed when I bought the machine.

I have tried updating the drivers on the network card but that does not seem to help. I also tried looked at the dumps with WinDbg to see if I could find a specific driver that was playing up. I also turned on the driver verification a couple of times to see if I could find a driver that was suspect -- that caused almost immediate crashes but I could not get to the bottom of what was causing it but it could make it happen by starting up Mumble.

The BSODs have so far seemed to happen when I am playing a game, using something like Mumble, or watching a stream.

From the below link download and install all drivers under LAN, Chipset and Bluetooth.
ASUS - Motherboards- ASUS P8Z68-V PRO/GEN3

Make sure all Windows updates are installed.

Turn Driver Verifier off.

The following drivers need to be updated:

Code:
LHidFilt.Sys    Thu Jun 18 02:49:39 2009
GEARAspiWDM.sys Mon May 18 22:17:04 2009
LMouFilt.Sys    Thu Jun 18 02:49:43 2009
These drivers can be found by searching them in Google and then finding the associated software or driver. Finally, find the latest version of this driver or software and download and install it. Some of the drivers may also be found here (if the driver says 'Windows Update' simply make sure all Windows Updates are installed).

You should also update any other drivers you can think of including graphics, audio, chipset, SSD etc.

I updated the drivers in the post above and the driver verifier is off. I also deleted my graphics card drivers and lets Windows update them for me. The BSODs are still pretty frequent but the connection is not dropped upon restarting. I've attached the newer crash dumps in case it is of any help.

HARDWARE
Run a chkdsk on the system partition to check for bad sectors or system errors.
Disk Check
Test your RAM using Memtest86+. Let it run until 6-8 passes have completed or errors have been found.
RAM - Test with Memtest86+
DRIVERS
Enable Driver Verifier. Enabling this should hopefully crash your system and then point to the faulty driver that is causing problems. However before you do, it is advised that you create a system restore point and backup first.
Driver Verifier - Enable and Disable

The graphics card driver should be manually installed. Please download the driver from the below link and perform a clean install (choose custom settings rather than typical).

Memtest and the disk check came back clear.

Using the driver verifier I was able to reliably crash my computer while opening Mumble. I isolated btath_rcp.sys (Atheros Bluetooth AVRCP Device) as the driver causing these verifier BSODs (logs uploaded for completeness).

I was not able to find an updated version of the driver so I have uninstalled it for the moment. I'm leaving the verifier on for the weekend to see if anything else crops up.

I would recommend disabling verifier, hopefully your system won't crash with it off.
