Windows 7: BSOD using Boot Camp on Mac Pro 2008 IRQ_NOT_LESS_OR_EQUAL

BSOD using Boot Camp on Mac Pro 2008 IRQ_NOT_LESS_OR_EQUAL

Hello,

As of last week I started getting a BSOD when using Boot Camp to start my mac in Windows.
There has been no appreciable change in hardware on the machine.
I only use windows to play games, the last game to be installed was Mass Effect 3, which I was playing when the first BSOD appeared.
Since then, I have been unable to start the windows partition natively.

Because I found a few threads stating that the error that the BSOD displays might be memory related, I booted in single user mode and checked the memory using applejack.

This checked out, so there must be something else that I am doing wrong.
I can start the windows partition using VMware Fusion on the mac side, so I was able to use the dump-tool to make a dump. I hope I did this correctly.

Can someone help me figure out what I am doing wrong?

Machine information:
Mac Pro 2008 (3,1)
2x quad core 2.8 GHz Xeon
10 GB DDR2 FB-DIMM
ATI Radeon HD 5770

Windows is on a different disk than my boot disk, a partitioned storage disk that does not see a lot of action other than being a boot camp disk:
SAMSUNG HD103UJ

Thank you for replying.
I have used windows in bootcamp since buying the machine in 2008.
First I used vista with bootcamp 1.0 and when 7 came out, I bought that when bootcamp 2.0 was released.
The drivers for boot camp were installed from a USB stick prepared by the boot camp assistant on the mac side.

Is there anything else that I can provide that might help track the problem down?

have you tried PRAM? when opening the mac press them until you hear the 3rd chime(loud tone on startup) and then release it, press command + shift + P + R this command fix hardware related issues
also try safe mode unistall ME3 and try reboot to normal.

Hello again, and thank you for your reply.

Good idea, I had not considered resetting the persistent ram yet.
Later today I will give that a try, though I am not too hopeful that will help.
Everything on the mac side works as well as it ever has.

As for uninstalling me3, do you really think that will help?
The crashes only started well into the game, a week or two after installing the game.
Regardless, I will try to uninstall the game sometime tomorrow and let you know what the effect is.

hmm.. i think the game crashed the operating system, sometimes the work load of the game primary the RAM crashes when it over laps.. i think you should check the game requirements..
When you said the ME3 installation then BSOD i am sure of it that it was the cause...
But better repair the OS sometimes it is damaged when having BSOD, open the installation CD of Windows it has a repair option there

Thank you for clarifying.
You could be right about the system specs, I did not check for the minimum requirements beforehand.

They are as follows:
Mass Effect 3 Recommended System Requirements

OS - Windows XP SP3/Vista SP1, Win 7
CPU - 2.4 GHz Intel Core 2 Duo (equivalent AMD CPU)
RAM - 2GB for XP / 4GB RAM for Vista/Win 7
HDD - 15 GB of free hard disk space
GFX - AMD/ATI Radeon HD 4850 512 MB or greater, NVidia GeForce 9800 GT 512 MB or greater
GFX RAM - 512MB (with Pixel Shader 3.0 support)

As far as I can appraise these requirements, it would seem that my machine matches or exceeds all of these requirements by a fair amount.

Using system repair is a good point. Unfortunately, that was one of the first things that I attempted.
The message that I received was "Startup Repair could not detect your problem".

It would seem that uninstalling ME3 is the only course of action that remains at this point.

Hello again, thanks for checking.
This morning I uninstalled me 3.

After uninstalling I conclude the following:
Windows still fails to boot natively.
VMware booting the bootcamp partition still works.

All signs seem to be pointing at a complete reinstall. Not a terribly exciting prospect.

Is there anything else in the crash dump that I posted that could be of help?

I think reinstall seems to be the last option for your iMac.
I dont know how to read the crash dump, only the admin know's the crash dump
i just helped you because i know how to troubleshoot a mac computer
last try open cmd as admin then type chdsk /f on your computer maybe it can help repair some bad sectors on windows.
