Windows 7: Asus G73SW Notebook BSODs

14 Apr 2011   #21

Win 7 Pro x64 SP1 OS X Snow Leopard 10.6.7

AVG had been causing issues with Windows 7 lately... I have no idea why the dump says unknown error.

Ok, thanks Dean.

The reason it says it's unknown is because your CPU is apparently in an invalid state:

It can't tell you what's wrong, because there's just no information on the CPU for it to disassemble. We know from the .bugcheck output that it was an attempted write by something to address 0x00000040, which is going to fail (it's within the first 64K of a process, in this case the kernel, and all VA in the first 64K is marked PAGE_NOACCESS). Other than that, though, without a *complete* memory dump there's no way to tell what's happening (and even with one, I can't guarantee 100% that it'll be found, but usually it can be done).

Thanks a lot cluberti, I'm not sure where to select "full" dumps, since the drop down menu only allows me to select between a minidump and a kernel dump (is that a full one?). I'll reproduce the BSOD with a kernel dump and post it here.

On that note, it is not a real BSOD, rather the screen turns black though all the fans are still running, lights still glowing and in that time it obviously creates a dump as well. Not sure if that helps or hints at something in particular. That black screen of death appears shortly after the windows symbol/animation, right before the login screen should appear.

Edit: This time the BSOD actually was blue again, not black. Not sure why the randomness...and I also couldn't sign in via "last known good configuration" anymore but had to get in via safemode to turn off verifier.exe. So it has 3 new dumps instead of one.

Once you've selected Kernel Dump (hopefully that'll be enough - otherwise it's registry editing time) you will need to reboot for it to take effect. Once rebooted, additional crashes will create a file in \Windows called memory.dmp. That will be the file we will need.

OK, I know why the context of the CPU is wrong - truecrypt. Not sure if that's the cause of the crash or not, but would it be possible for you to decrypt and remove this during troubleshooting? The reason I ask, is this is the last thing that was done before the box crashed. The originating IRP is pending in a truecrypt IRP, which seems to obfuscate everything (given what truecrypt does, I suppose this is expected):

Thanks for the breakdown.

Interesting, so truecrypt encrypts the whole...erm...kernel or what does it do? Because I only use it to encrypt a handful of personal documents and I disabled it to automatically start up with the system so I'm not sure why it even does this stuff. I also updated to the newest version but that didn't seem to help either.

I'll get rid of that program then and run verifier.exe again to see if this time the system can start up without a BSOD. Thanks again!

Johnm123, I got the dump from your last PM, and frankly it doesn't give any further insight. Also, some of the context is screwed up, so it's not all there. Honestly, at this point, we need you to configure the system for a complete memory dump, and manually configure your paging file to be both min and max RAM+50MB. To configure for a complete memory dump:
  1. Open sysdm.cpl
  2. Click the "Advanced" tab, and click the "Settings" button in the Performance section
  3. Click the "Advanced" tab, and click the "Change" button
  4. Click "Custom size", and enter (in MB) the same value for both the "Initial size" and "Maximum size" boxes - your system's RAM+50MB (so if you have 8GB of RAM, you would enter 8242 - 8192 is RAM, +50 = 8242).
  5. Open regedit
  6. Browse to HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management
  7. Change the value of the DWORD "CrashDumpEnabled" to 1
  8. Reboot
Now, do NOT go back into the system control panel and touch anything - the moment you view the memory dump dropdown and then click OK (even if you change nothing), it'll change the CrashDumpEnabled value back to 2 (kernel dump only). If you do the above, in that order, and *only* the above, the next crash should be a *complete* memory dump, including all user and kernel-mode contexts (let's hope!).

Thanks a lot for this step-by-step tutorial. I did everything except the regedit part because that "CrashDumpEnabled" option just wasn't there. Any ideas? (screenshot attached)
