I am getting a blue screen after I attempt to login to a pc.

Verification error in wmiacpi.sys (WMD driver error) 20e

wmiacpsi.sys = 152f at B9BAB852F

I have run the Dell diagnostic and everything passed.
This is a Dell laptop latitude D531. Dell just replaced the hard drive about 10 days ago. It worked fine until Monday.

Any any what this may be?

Are you sure of the spelling of the 2nd file name? If so, Google doesn't give any results for it - which is suspicious.

The first file name ( wmiacpi.sys ) is a Windows file that's used to help manage the ACPI settings in your system. http://www.bleepingcomputer.com/filedb/wmiacpi.sys-7763.html

A BSOD error will usually point to the file that the error occured in, but this may not be the source of the error.

Here's a link on how to find more info about the BSOD message: http://www.bleepingcomputer.com/forums/top...tml#entry409491

Once you locate the .dmp files for the event, you can use this link to generate an analysis of the dump for us to have a look at ( http://forums.majorgeeks.com/showthread.php?t=35246 )

The drive was replace a little more than a week ago. The only drivers on it are the ones Dell installed on the hard drive before the tech replaced it.

They say it is the motherboard and will be out to replace it on Monday.

Hmmm, let us know if it really is the motherboard :thumbsup:. That's very good customer service.

Must be a known defect that they don't spread around.

Well it wasn't the motherboard. They also replaced the memory.
It still failed the extended memory test.
They will be out today to replace the processor.
