Device Got Stuck In An Infinite Loop Blue Screen error researchedon



This was one of the threads I found on ngohq forums - all credis go to
the author, some people will probably benefit from this info as did I...

Hi there:

I'm very happy and I want to share my experience fixing the random
reboot while playing games.
The BSOD related to the "ati3duag.dll". I have to say for sure, I've
finally fixed it, and I want to share the "more official" solution to
the problem. (At least official for me). I really want you to read this,
even if it's long because you will find answers to many common problems.

I want to document the problem and I will cover all the bases because
I'm sure it will help every ATI RADEON user.

My Former System:
Case Antec P150
ASUS P5W DH Deluxe
PSU Seasonic S12 500W
4GB Corsair Dual Channel 4 Sticks of 1GB each (DDR2-800)
Sound Card : Soundblaster Audigy SZ2
WD 250 GB HD 7200RPM
Catalyst Drivers 6.8 with CCC.
Windows XP Pro SP2.

Mini Chapter 1 : IT'S NOT THE SOUND CARD.

1) The problem is, and I know you guys know it. You are playing any
particular game and you are about 15-30 minutes of play, and then a Blue
Screen, BSOD appears saying something about a sound driver, and the
stuttering noise of the game.

Yeah, that was the infamous "squeal of death" reported on many CREATIVE
sites. (google "squeal of death", and you'll find thousands of posts)

After trying over and over to fix the problem, I've decided to give up
with my Soundblaster Card, and got myself a Bluegears B-Enspirer sound
Device which I really recommend everyone, because it's powerful, and a
comparable low CPU consumer like the Soundblaster.And also it's reported
to have great solid drivers for both XP and Vista.

I cleaned all the Creative drivers, and even used drivercleaner to get
rid of them. Then installed the new sound card drivers.

I fired a game , Tomb Rider Anniversary. And played, thinking my
problems were solved.
And then after an hour, I got another BSOD with the same exact
stuttering (squeal) like the Soundblaster did.

I took the minidump file and debugged it and it reported a
"IRQ_NOT_LESS_OR_EQUAL" and having guilty the "cmaudio.sys" driver from
the new sound card driver. That means, two devices are sharing the same
port, and might conflict between each other, depending on how the memory
addresses requests from each one of the devices.

2) Interesting, the older and new card were located on the lower PCI.
I've found in my Device Manager (Control Panel) by checking the
devices "by connectrion" that the cards were sharing an IRQ with a
J-Micron (SATA controler).
Of course, I've opened my case and took the sound card out, and moved it
to the PCI socket, right above it.

When I started my machine again, I've checked the Device Manager again,
and this time it showed me that the soundcard was using now
a clean IRQ# 23 just for it, no sharing.

Ok, sure, now the problem is over...
I've fired up a game again "Lost Planet Extreme Condition", and guess
what, BSOD, with a squeal, again.

realeted to the "ati3duag.dll"

SYMBOL_NAME: ati3duag+4b3c8
MODULE_NAME: ati3duag
IMAGE_NAME: ati3duag.dll
STACK_COMMAND: .cxr 0xffffffff984ac80c ; kb
FAILURE_BUCKET_ID: 0x7E_ati3duag+4b3c8
BUCKET_ID: 0x7E_ati3duag+4b3c8
Followup: MachineOwner

Ok, I got a BSOD, but definetely I got rid of the IRQ_NOT_LESS_OR_EQUAL
BSOD, by putting the sound card on its own unique IRQ.

From there I can proceed to isolate the problem even more...


I've started to pull my hair out. And rapidly got into forums trying to
investigate what the heck ATI3DUAG.dll is.
The web is plagued with sites and people talking of a random BSOD
related to this file, there is also information in other languages
(german, french, spanish)
But no one really tells you what ATI3DDUAG.dll is. I found out it is
somehow related to the anti-aliasing feature on Catalyst.

They tell you :

a) It is a driver problem, just get the newest drivers. So I got the 7.6
and even tried the 7.7

b) Replace the ATI3DUAG.DLL file with an older one, it might be corrupted.
I've tried both solutions and then guess what, something interesting

I've got a BSOD but this time the blue screen didn't give me anything
related to a specific driver.
It was a 0X000008E bug, or 0x8E, but again didn't say anything about
what driver was causing this.
I used a debugger to check the minidump and i got this:

Debugging Details:

EXCEPTION_CODE: (NTSTATUS) 0xc0000005 - The instruction at "0x%08lx"

So, first the ATI driver ati2evxx.exe caput, but then NTKRNLMP.EXE
capput-ed as well.

Mini Chapter 3 IT'S NOT THE MEMORY

Probably, like me you've read this many many times on the web. "It's a
bad memory stick" "One of your sticks is faulty"
Fine, why not. I can talk with Corsair, no problem they can send me a
new stick under my waranty, but ONLY IF I INDEED have a defective stick.

I let my computer run Memtest +86, ON ALL STICKS first at for about 10
No errors whatsoever.
Then I ran Memtest +86, but now on EACH of the Sticks 10 times:
No errors again.
No memory issues., period.

In fact my computer never ever crashes while using any application. The
BSODS happen only while running games.
So I definetely discarded that this could be a memory issue. I would
definetely be in favor of this to be a memory issue if my computer
crashes randomnly for any reason other than games.


Again, you've heard this many times. "Then it's your power supply going
wacko on you", "You don't have enough juice for your video card",
"Your PSU is giving up".

Sure, I have a Seasonic S-12 500W power supply, which has enough amps on
the 12V rails to actually power the X1900XTX very stable.
But why not? It has been a year since I've purchased this PSU, and
probably it started to give up.

Anyway, I'll probably need a better power supply to feed the newest
cards, 8800GTX the Ultra, the Radeon HD 2900XT or XTX or whatever comes
after the R600 chip from ATI.

So I purchased a Corsair 620HX, which has been reviewed as one of the
most stable and efficient power supplies on the market, and it even
capable of powering
two 8800GTX on SLI mode, no problem and stable, thanks to its strong
amperage on the 12V rails, adding up to 54 amps. (Correct me if I'm wrong)

This should be by far more enough to power my X1900XTX, piece of cake.
I installed the new power supply and tested my system.

New system now:

Case Antec P150
ASUS P5W DH Deluxe
PSU Corsair HX 620W
4GB Corsair Dual Channel 4 Sticks of 1GB each (DDR2-800)
Sound Card : Bluegears B-Enspirer
WD 250 GB HD 7200RPM
Catalyst Drivers 6.8 with CCC.

Results: Guess what. I have a magnificent Blue Screen of Death after
playing for 30 minutes. Same bugcheck.
It's not the power supply, period. The possibility of having two power
supplies going wacko is very minimal.


I flashed my bios to the new revision. And it didn't help at all. It
only helped reorganize the memory better, so instead of having 3 GB
recongized in
Windows XP, now I have 3.12 GB. Wow!! But nothing more.

Remember, 4 GIGS can only be used in 64 bit OS.
So, it's not the BIOS.


I used to play games perfectly with my machine. And frankly don't know
why I cannot play any games anymore without a random BSOD. It's because
they are new? Is it because they draw much more power and requirements
from my machine?

Is this a trend or a pattern on newest games to just crash critically on

I've checked the temps on my CPU: Dual Core X6800 2.93Ghz cooled by a
Scythe Ninja, which IMHO is an overkill for this processor.
It doens't go above 35C on load and it's summer, and I have 80F ambient

All my memories have heatsinks. They are warm, on load, but nothing to
worry about.
My GPU cooler is made by HIS, and it exhaust the hot air outside my
case, and it's also very silent.

Checked the temps on my GPU running Lost Planet with all high settings.
It doesn't go beyond 85C after playing, for, let's say the time I can
play without an BSOD.
Negative pressure is very good inside my case. All the hot aire is being
pulled out by two 120mm fans plus the Radeon's exhaust cooling system.
It has been cool before, and it' cool now nothing to worry about.

So what the hell is it?

Mini Chapter 7 IN DEEP RESEARCH.

At this point, I was having many weeks of investigation, pulling my hair
out, many nights of investigation in google, different forums blogs,
translating french and german pages that talk about it.

Many questions, same useless or undocumented answers, and sometimes,
even silence on the forums regarding these issues.

I was thinking to myself, that this was the end of the PC Gaming for me,
that now you cannot trust any brand, they all lead to the same crappy or
unstable drivers, expensive videocards that two months later cost nothing.

Why should I spend a single more dime on new technology to power up my
rig and play games?
Should I just get an XBOX 360, and forget about spending stupid money on
a PC? Losing my ability to use the mouse to play 3D shooters? ( I just
CAN'T :-()

Then I've found something very interesting.

During my long research on bugchecks from many people on the web having
audio driver problems, or that stupid ATI3DUAG.DLL BSOD

All of the buchecks I studied will mentioned these drivers:


You will always find them on any debugged minidump related to this BSOD.
Have you noticed it? Because this leads to my conclusion on the problem.


I always make and keep images of my current system. And I do prefer
TrueImage over Ghost. When the system gets screwed I ussually recovery
from a mess uing an image.
But his time I decided finally to make a clean install of Windows XP.
And I wanted to make things very carefully, to finally identify the problem.

Sorry for the long thread, but I'm documenting how I've isolated the

1) First formatted the hard drive (a real format, and NOT a quick one).
I wanted to make sure to be free of any potential rootkit.

VIDEO DRIVERS YET. (Helps isolate problems)

3) Downloaded and installed all the updates, and also installed the .Net
Framework 1.1 (Just in case) Also please DO NOT install any audio or
video drivers
offered by Windows Update.

4) Installed all my usual programs (OFFICE, PHOTOSHOP, NERO), but DO NOT

5) In other words have your system ready, but DO NOT INSTALL ANY AUDIO

6) Backed up this clean configuration on a TrueImage Image, to have it
ready, just in case something gets screwed.

Then, and only then I proceeded to install my Video Card Driver. But I
installed the Catalyst Driver only. NO F...ING Catalyst Control Center.

I've decided, this time I didn't want any bloatware on my machine for
good. So I got to NGOHQ and installed the Old and great Catalyst Control
Panel. (Thanks to NGO and Regeneration for his work on drivers)

I've installed CAT 6.7 the only version that gave me at best experience
with my current video card.
After that I've installed my soundcard driver.

Then suddenly the most interesting and miraculous thing happened!
For some reason I've clicked on Windows Update and by surprise I saw two
critical updates:

"Install this update to prevent an issue in which you may receive a
“stop 0x7e in aec.sys” error message on a computer that is running
Windows XP Service Pack 2. The error may occur during startup, or after
the system has started. AEC.SYS is the acoustic echo canceling driver."

This is a reliability update for Windows XP machines. Install this
audio component update to prevent memory corruption issues which may
cause an unstable state on a computer that is running Windows XP
Service Pack 2. After you install this item, you may have to restart
your computer.
"You may experience one or more of the following symptoms when you try
to play audio files on a computer that is running Microsoft Windows XP
Service Pack 2 (SP2):• When you resume audio playback after you pause
it, the audio playback does not play the audio file from the correct
position. Instead, the audio playback resumes from a random position on
the audio track.
• You randomly receive the following Stop error message during audio
file playback:

Note If one or more of the following audio drivers are being used when
you install this update, you must restart the computer. This enables the
functionality of the following files:
• Kmixer.sys
• Splitter.sys
• Wdmaud.sys

Interesting isn't it?
Of course!! It happens that all the bugschecks I've seen of the web from
people with the same problems always mentioned AEC.SYS, KMIXER.SYS and
SPLITTER as unloaded modules.
It's more interesting to notice that this type of BSOD happen more
concurrently with games that use reverb or echo sounds, like happened to
me with BF 2142, Tomb Raider Anniversary and Lost Planet. Games that
have echo all the time.

So I went ahead and installed these updates that were offered.

One month from this and counting.

Believe me, until this day I've never ever have another BSOD. I've been
playing all these games again for more than 5 hours, fearing that this
nightmare might happen again, but it didn't.

Now all this fear, and frustration is left behind, and now I can finally
start enjoying playing in my PC again, feeling safe and happy.

At the most I've had one crash in one game, but a CTD. A crash back to
desktop, without a message, but not the horrid Blue Screen of Death or a
Squeal of Death.

So the solution, I think it's on these two Microsoft updates. I
sincerely think it has to do with sound, but it's not your soundcard,
the problem
resides on the windows drivers that work hand-hand with your specific
soundcard drivers. And I think it's related to the echo (aec.sys).
Remember that in all BSOD's we have stuttering or a squeal in the sound,
that gets repeated while you see the blue screen.

Other recommendations:
- I think it also helps to make a clean-clean Windows install
- Don't mess too much with registry cleaners.
- Refrain from installing the CCC, and really make ATI wake up and give
customers an utility other that the bloated CCC.

I really wanted to share this, because I think it would really help
hardcore PC gamers like me who spend money to have our machines fine.
There's been so much silence and lack of investigation, and I think it's
because this research took me time and months, to finally discover the
I don't think that video and sound card manufacturers have the time and
dedication to nail the problem, or maybe even the motivation. But I do,
and I'm sure
you have the motivation too.

And now, let's play. ""
