Windows XP Stop Error 0x000000B8

I am running Windows XP SP2 Home Edition on a Generic AMD PC. I receive this BSOD error "0X000000B8 A wait operation, attach process, or yield was attempted from DPC routine". This error appears at different times but, I can recreate it by running a virus scan with McAfee Version 9. XP was installed a week ago and the installation went fine as well as all the current Microsoft updates. It was a clean install. Here are the applications that are installed. McAfee Antivirus 9, Yahoo Messenger, People PC, Microsoft Antispyware, a web cam, and XP Home.

Any help would be greatly appreciated!

First of all be sure to upgrade your McAfee, maybe it has some compatibility issue with your system.

Then make sure you don't have any virus: AVG free edition is my tool of choice ( ) , but also Panda On-Line ( ) is a good "one-shot" tool.

Don't understimate spyware: in my ICT career, I saw many pcs stalled due to bad coded spyware running in background: IMNSHO there isn't any antispyware tool being better then others, I use to run them all (not simultaneously, of course!!)

* Spybot S&D ( )

* Ad-Aware ( )

* Ms Antispyware ( )

Also try to check your ram, maybe it is faulty: my tool of choice is MemTest86 ( )
here is what MS says about it :
When Windows crashes with blue screen, it writes a system event 1001 and a minidump to the folder \windows\minidump
Check system event 1001 and it has the content of the blue screen

Control Panel -> Adminstrative Tools -> Event Viewer -> System -> Event 1001. Copy the content and paste it back here

Zip 5 to 6 minidumps and attach the zip files at any webspace. I will study the dump and find out the culpri

I have downloaded the memory test application and will run that to find out if I have a bad module - great idea. I will also retrieve the system event logs and post them to assist as soon as possible.

The MS support link posted is in reference to Windows 2000 and the error message is slightly different than the one i am receiving - I did search MS and found nothing specific to Windows XP on this exact error : |

More info soon - Thanks

I have ran two different memory testing programs (CheckIt and MemTest86) with no errors in the memory. I also used CheckIt to scan the rest of the hardware and everything looks fine on the hardware test results.

Here is the application event error log which is generated prior to the stop error. Hopefully, this may provide some insight as to the cause of the stop error 0X000000B8.

Your windows has various bugcheck code 8E,  B8, C2 and D1. The analysis reports of two minidumps show that NaiFiltr.sys which belongs McAfee and one analysis report shows vvoice.sys (HSP Modem device driver).  De-install McAfee and upgrade vvoice.sys to latest patch. Your Windows

Your windows may have multiple culprits.Your Windows have 6 minidumps crash with bugcheck code 8E and their symptoms look like faulty RAM. I would prefer you to implement the solution without money. As there have two culprits. I suggest you to de-install NaiFiltr and upgrade vvoice.

If the windows still crashes, attach the minidumps here. I will confirm whether it is faulty ram issue.

Here is a link to the dump files. This is driving me crazy lol

Let me know if you have any other ideas.

Does anyone else have anything to add that may help?

For now I have removed McAfee and installed Norton which seems to have reduced the bsod however, it still appears from time to time. Mostly now when I am on the internet.

Thanks in advance
Attach the latest minidumps at the webspace. Maybe your problem has multiple culprits.
