Windows 7: Random Bluescreen 0x0000001a

Yes, this is what is bugging me. I was very proud to get W7 up and running stable on this old girl (and they said it could not be done!) and it ran without a problem for a long time. So now I did something and screwed it up. I pushed it one step over the line!

I will experiment with it and let you know what I find.

Hi Archie

Got a new bluescreen last night. This one was REFERENCE_BY_POINTER, Stop 0x00000018. This one came while it was recording TV.

I'd just like to know if it is the same driver.
I have not had time to try the tests we talked about. Probably this weekend for that.

New Grabs below. Thanks man.

Mate, it is stop 0x18, as you said.

REFERENCE_BY_POINTER (18)
Arguments:
Arg1: 852478e0, Object type of the object whose reference count is being lowered
Arg2: 85466d48, Object whose reference count is being lowered
Arg3: 00000001, Reserved
Arg4: fffffffe, Reserved
    The reference count of an object is illegal for the current state of the object.
    Each time a driver uses a pointer to an object the driver calls a kernel routine
    to increment the reference count of the object. When the driver is done with the
    pointer the driver calls another kernel routine to decrement the reference count.
    Drivers must match calls to the increment and decrement routines. This bugcheck
    can occur because an object's reference count goes to zero while there are still
    open handles to the object, in which case the fourth parameter indicates the number
    of opened handles. It may also occur when the objectís reference count drops below zero
    whether or not there are open handles to the object, and in that case the fourth parameter
    contains the actual value of the pointer references count.

But, it is also showing nothing.

From Carrona.org, STOP 0x00000018: REFERENCE_BY_POINTER
Usual causes: Device driver, kernel, hardware

About hardware, we have the knowledge that it is old. But, we need to check for the drivers once again, as nothing is stressed in the dump.

Well, in the weekend then

I've just disabled the Soundmax Device. We will see if that makes any difference between now and then.
Thanks again!

You were right on about the sound drivers Archie. They are none-the-good.

However, the system crashed once again with the sound device disabled.
Stop 0x8E. This one occurred going into sleep mode.

I ran a bunch of tests this morning with Driver Verifier. This is what I found:
  • All non-Microsoft drivers (that are not sound related) work (no crashes when I check these individually)
  • Sound drivers definitely crash. portcls.sys and smwdm.sys. (dmk.sys is OK.)
  • Selecting only Microsoft drivers, but not any sound drivers or non-MS drivers, also crashed. Stop 0xC4.
The last dump file is the one where the crash occurred with just MS drivers - no sound.
Do you see anything different in that dump?
TIA

You are a real geek, TVeblen You used DV beautifully.

There are five crash dumps in the zip, and all are stop 0xC4, DRIVER_VERIFIER_DETECTED_VIOLATION.

And, all of them are caused by SoundMAX Integrated Digital Audio driver (smwdm.sys) and Andrea Electronics Corp Audio Noise Cancellation Driver (aeaudio.sys). All are almost the same.
Code:

Use !analyze -v to get detailed debugging information.

It is from the last one, 04/11/2012; 11:40 AM.

But unfortunately I haven't found a crash dump with the Stop 0x8E. It is very difficult to infer about it without seeing the dump, coz it covers a wide area.
STOP 0x0000008E: KERNEL_MODE_EXCEPTION_NOT_HANDLED
Usual causes:
Insufficient disk space, Device driver, Video card, BIOS, Breakpoint in startup without having a debugger attached, Hardware incompatibility, Faulty system service, 3rd party remote control, Memory.

Can you not make it sure about one, without seeing the crash dump

So.... what to do next ?

Ach! Such a dummy! I ran CCleaner to get some nice clean dump reports and deleted the dump with the 0x8E. Excuse me while I give my self a good dope-slap.

There, that's better!
I can't thank you enough Archie. I feel it is pretty obvious what is going on with this old Betsy. I'll play with some more drivers and keep my eye on it. Maybe even find a PCI sound card, with at least Vista drivers, on EBay! I won't waste any more of your time with the obvious. I know you guys are busy over here!

TVeblen, how much I may be busy, you are always welcome, and your issue is the priority.

If your computer is not running at its best, a lot of OPs will suffer there

Oh! MY computer (the one in my specs) runs smooth as silk!

This old Pentium 4 machine has been downgraded to the PVR station. Not that recording TV programs is a minor job.
Here's how it works:
  • I build a sate-of-the-art new machine for myself (goes my office)
  • The PC that was in my office gets demoted to Family PC
  • The Family PC gets demoted to PVR PC
  • The PVR PC gets sold off for parts.
And it's looking real obvious that I will be building a new machine this winter!
