IRQL_NOT_LESS_OR_EQUAL (0x0000000A)

Sure - send it.  Sometimes folks can come up with 5 easily and want to send them all, but I think the last 5 are adequate!  If I don't look at it right away, somebody else will see it.

12 hours is plenty of time to run MBAM and SAS too.

Now that your BSOD knows you are looking for it, it may evade you.

Describe your current antivirus and anti malware situation:  McAfee, Norton, Spybot, AVG, Avira!, MSE, Defender, ZoneAlarm, PC Tools, Comodo, etc.

Since you mentioned audio, might as well check it out while we are waiting (and video info won't hurt):

Please provide additional information about your system:

Click Start, Run and in the box enter:

msinfo32

Click OK, and when the System Summary info appears, click Edit, Select All, Copy and then paste the information back here.

For video driver information, expand the Components, click Display, click Edit, Select All, Copy and then paste the information back here.

For audio information, expand the Components, click Sound Device, click Edit, Select All, 

Copy and then paste the information back here. 

There will be some personal information (like System Name and User Name), and whatever appears to be private information to you, just delete it from the pasted information.

This will minimize back and forth Q&A and eliminate guesswork.

Sorry -- yes, that other stuff (small memory dump, and the path to the minidumps) was already exactly as you specified.  Which leaves me puzzled as to why I don't have any dumps to look at right now.  But hopefully the next BSOD will generate one.

The last two came about 12 hours apart (about 11:30 last night, after I went to bed, and about 11:45 this morning).  But, typically, it can go a day or two without happening.  Do you not want me to send the dump information the next time I get one (and wait until I get 5 of them)?

Good job.

Did you set up the other stuff too (small dump, to the Minidump folder, etc.)?

When you get some recent dumps, do this with your BSV:

If you double click on of the dumps, you will get some information about it (including the Caused By Driver field) and you may be able to spot the problem right away - especially if you see a pattern in the dumps where the Caused by Driver field is the same (start with that driver).

Select (highlight) one or more of the most recent dump files by clicking them and holding down the Ctrl key to select multiples files.  Try to select just the most recent ones that relate to your issue (maybe five or so dump files to get started).

Click File, Save Selected Items and save the information from the dumps to a text file on your desktop called BSOD.txt.  Open BSOD.txt with a text editor, copy all the text and paste it into your next reply.

Here is an example of the BSV report from a single BSOD that I initiated on purpose that shows the cause of the crash as the i8042prt.sys driver belonging to Microsoft Corporation:

Send the information from the last 5 memory dumps.

The "Write an event to the system log" and "Send an administrative alert" boxes were already checked.  I did uncheck the "Automatically restart" box.

NVIDIA reports that no driver updates are needed.

I would use BlueScreenView too, but perhaps your XP is not set up to log these events, create dump files or put the dump files where BSV expects to find them by default:

XP is set up to automatically reboot on some system failures, so you need to disable that feature so the BSOD information will stay on the screen for you to see it.  You can also configure XP to log an event and create a memory dump file in a specified folder for each BSOD.

Configure your system to not automatically restart on system failure (that is what it wants to do):

Right click My Computer, Properties, Advanced, Startup and Recovery Settings.

In the System failure section:

Put a check mark in the "Write an event to the system log" box

Put a check mark in the "Send an administrative alert" box

Uncheck the "Automatically restart" box

In the Write debugging information section, choose:

Small memory dump (64 KB)

Set the Small dump directory to:

%SystemRoot%\Minidump

Click OK, OK.

Restart your computer and wait for the next BSOD (not very exciting, this waiting...).

While you are waiting, you should also verify your NVIDIA drivers as follows:

I would navigate to the NVIDIA website and let their online scanner take a look at your video card and see what it suggests for drivers and consider their analysis if they suggest a new driver.

It is recommended to run the NVIDIA scan with Internet Explorer.

Here is the address to the NVIDIA page:

http://www.nvidia.com/Download/PreScan.aspx?lang=en-us

Read the directions, then click the GRAPHICS DRIVERS button to start the scan.

Optional, but recommended:

Download, install, update and do a full scan with these free malware detection programs:

Malwarebytes (MBAM):  http://malwarebytes.org/

SUPERAntiSpyware: (SAS):  http://www.superantispyware.com/

They can be uninstalled later if desired.
