received BSOD - C9 - PGPwded.sys **Note - no dump is generated in this case**

Still no crash dump .... not an usual case. One possible cause is the HDD is becoming inaccessible when the BSOD is taking place.

Anyway, Stop 0xC9 means DRIVER_VERIFIER_IOMANAGER_VIOLATION, which ensures that the DV was active there, and it points the driver PGPwded.sys as a problem causing one.

You said it earlier ....

My hdd is encrypted by Symantec PGP - as required by my employer.

But you can see it clearly that the PGP Storage filter service is causing issues for you. And in that case, you must to get rid of Symantec, at least on a test basis.

From your words it appears that it is an office computer. In that case, as you cannot uninstall Symantec, you contract the IT department of the office. They may have some good idea as to how the BSODs can be stopped without removing Symantec.

Thank you very much! I do not understand why the failures began with a BSOD pointing to netio.sys and now is a PGP issue - but only when I run verifier. I still think I will get a random netio.sys BSOD which does produce a dump. When that happens I would appreciate your help diagnosing that. Thank you again.

Many a times it is seen that a natio.sys BSOD is occurred due to the symnets.sys, Symantec Network Security WFP Driver; or teefer2.sys, Symantec Endpoint Protection Firewall.

The other opssibility is the network driver itself, and apparently there is a possible update to your Intel® Centrino® Advanced-N 6235, Intel® PROSet/Wireless Software and Drivers for Windows 7. You should try to apply it.

I have suggested you to uninstall McAfee Security Scan Plus in post #2 but you havent done it, too. Saying it again, it is not something that you want. You have got it unintentionally. This will not do any good for you, and having McAfee in your system is enough of a problem.

One very common source of McAfee Security Scan Plus is flash player update, as the users dont bother to uncheck the bloated things.

Attachment 334089

Adobe gets money form McAfee for advertising their product; and you get some trouble due to carelessness.

Thanks Arc. Unfortunately my BSOD troubles began with updating the Intel® Centrino® Advanced-N 6235, Intel® PROSet/Wireless Software and Drivers for Windows 7. I had to roll them back and still received BSODs on netio.sys, albeit not every few minutes. Re: McAfee - I did remove it per your instructions. It doesn't show up on my installed software list. I will try it again. I understand how it slips in with other apps - I must have let my guard down one time. After I try the removal tool again is there some way to verify that it is completely gone? Thanks.
