(Random?) BSODs on Windows 7 x64

btwthieves · 05 Jan 2010

For a few months now, I've been experiencing seemingly random BSoD restarts in Windows 7 x64. I've attached minidumps from my last seven crashes. These crashes happen when I'm playing 3D games, when the CPU is idle, or when I'm searching these forums for a solution in Google Chrome

I've tried to interpret these minidump files using BlueScreenView, WhoCrashed, and Windbg.exe. BlueScreenView and WhoCrashed blame ntoskrnl.exe, WDF01000.sys, and occasionally ataport.sys for the crashes. I'm not sure Windbg.exe is configured properly, but it says KeyMagic.sys is causing problems.

As one thread on these forums suggested, I downloaded and installed the latest drivers for my nVidia GeForce 9800M graphics card (from the nVidia website, not Windows Update) but have, of course, crashed since then with the same errors.

It should be noted that I'm running this particular installation on an NTFS partition on a Macbook (Late 2008 model) with OS 10.6.2 SL and Boot Camp v3.0, which is capable of running Windows 7 x64.

Any ideas?

Thank you for your time.

Edit: I've also tried SFC /SCANNOW as admin but it came back clean. I've disabled/uninstalled *all* antivirus software and firewalls, except the stock Windows Firewall.

I've seen the keymagic errors in BootCamp installations before - so I'd suggest updating your keyboard drivers from the Apple website. I do see those same errors in the memory dumps that you've uploaded - and the debugger does blame it for the crashes.

Also, Please update or remove these older drivers that were loaded at the time of the crash. Don't use Windows Update or the Update drivers function of Device Manager. Please use the following instructions to locate the most current drivers:

How To Find Updated Drivers:
- search Google for the name of the driver
- compare the Google results with what's installed on your system to figure out which device/program it belongs to
- visit the web site of the manufacturer of the hardware/program to get the latest drivers (DON'T use Windows Update or the Update driver function of Device Manager).
- if there are difficulties in locating them, post back with questions and someone will try and help you locate the appropriate program.

Here's the older drivers:

Code:

bcmwl664.sys Wed Oct 22 20:41:31 2008
IRFilter.sys Wed Jul 02 15:53:12 2008
nvmfdx64.sys Tue Jul 08 05:18:13 2008
nvsmu.sys    Tue Jul 22 13:21:00 2008
