XPS 600 Blue Screen Errors

About a week ago, I chatted with support rep. re:  intermittent blue screens of death that were taking place on my system (XPS 600), and had been for the last 3 weeks to a month.  At the time, I hadn’t captured the stop error message.  I had run the Dell driver test with no errors.  I had checked to make sure that there were no updated drivers to be installed.  The system has always been protected by Virus software, and Norton is not detecting any viruses.  I’m also familiar with virus behavior, and I don’t believe I’m dealing with a virus – any that I have seen before.

He reviewed the minidump files and found no helpful information.

He downloaded to my system a memory test and burned it to a CD for me to run.  I ran the memory test.   I also ran the troubleshooting tests for blue screen errors which took about 24 hours to complete.   These all passed.  

He said that I had a lot items in my startup and were present in RAM, so I have been slowly turning off things that are not required.  

He asked about peripherals and setup:

I am on a small peer to peer Microsoft network, mainly for file sharing and printer sharing.   There is a cable modem with a router attached that the computers are connected to.  The machine that I’m on is an XPS 600.  The other machines are an HP laptop and another Dell Precision 450.   The printers are an HP Laserjet 1300, which is connected to the XPS 600 via a USB port and a Canon iP6700D that is connected to the Precision 450.

We have also experienced some blue screen errors on the Precision 450 that referenced the video driver.  

XP Professional is running on both machines.  SP2 is in installed on both machines.

Both machines have Norton Internet Security 2007.

Most recent changes:

The Canon was installed about a month ago, attached to the Precision machine.   However, I do have the Canon software installed on the XPS600.  I can use this through the peer to peer network.  I don’t remember problems immediately taking place after this install.  However, it may be a player.  

I installed the most recent version of Windows Media Player.

I have automatic updates turned on for both Norton and Windows.   So these install in the background frequently. 

The above changes are also true for the Dell Precision 450 machine, which is also experiencing blue screens. 

I have since captured the stop code:  0X000000C5.   I believe the first code is the most relevant, but I have the rest if you need it. 

The initial errors message said to test the drivers, and if necessary to enable special pools.  However, no specific reference to the offending component. 

I used Verifier.exe to test the drivers.  First, I tested all drivers, and that yielded a 0X000000C4, Device Driver attempting to corrupt the system has been caught.  The faulty driver on the kernel stack must be replaced with a working version.  However, I discovered that this is an error verifier.exe will yield if Norton is installed.  

I narrowed my test to unsigned drivers.  It passed the boot. 

I then selected all drivers except Norton/Symantec, and it passed the boot. 

I then downloaded the Microsoft Windows Support tools to get the gflags.exe program, so that I could turn on the pooling option.  I only downloaded the software and had not changed any settings yet. 

I then turned off all of the verifier.exe settings, and rebooted.  It bombed with a blue screen, with a 0X000000C5.  However, this time it identified when I reported it to Microsoft, I got new troubleshooting information:

Option 1:  Install the most current device driver for your video card. 

Option 2:  Manually decrease Hardware Acceleration for your video adapter.

Technical information:

Error Message:  Stop 0X000000EA THREAD_STUCK_IN_DEVICE_DRIVER (Q293078)

My only issue with Option 2 is that this system has been working flawlessly prior to this, so unless the video card has an incompatibility with the new Windows/Norton/Canon/Media Player software, the hardware itself should be compatible, and I did not want to degrade performance.

I executed gflags.exe, and I checked the enable pool tagging flag.

I did receive another error, the same as above once during the evening.  Same information related to the 0X000000EA above.  However, I now have activity in the Windows System Event Viewer:

Error code 100000c5, parameter1 00000004, parameter2 00000002, parameter3 00000001, parameter4 8054afd2.

Other severe errors  or warnings in the Event Logs:

System:

The following boot-start or system-start driver(s) failed to load:

nvraid

DCOM was unable to communicate with the computer SWEENEY2 using any of the configured protocols.

Application:

MiInstaller error (Lots of these)

Windows saved user SWEENEYXPS\Laurie Sweeney registry while an application or service was still using the registry during log off. The memory used by the user's registry has not been freed. The registry will be unloaded when it is no longer in use.

 This is often caused by services running as a user account, try configuring the services to run in either the LocalService or NetworkService account.

So I think I have a lot more information, but I still have an unstable system.  It may be fine for a couple of days, and then crash.  Or I may wake up in the morning to a blue screen.

Anybody have any ideas?
