Howdy,

Windows XP SP2 gave me a BSOD today when I was logging in after a fresh reboot... I've tried to track the cause down and have hit a brick-wall due to my lack of knowledge of Windows Debugging.

Any help you could offer would be greatly appreciated!

The BSOD error message is:

"Driver_IRQL_NOT_LESS_OR_EQUAL"

Microsoft's Error reporting wizard gave the following info:

BCCode : 100000d1
BCP1 : 000000ED
BCP2 : 00000002
BCP3 : 00000000
BCP4 : 000000ED
OSVer : 5_1_2600
SP : 2_0
Product : 768_1

A google search turned up the fact that this is probably related to an "out of date" driver... One that's not compatible with XP. So now I'm trying to figure out which driver has caused this BSOD.

Since the crash generated a memory dump, I took the mini-dump file that it generated and analyzed it with MS's DUMPCHK.exe and here are the results:

Finished dump check
============

The problem is I don't know what any of this means.

Two questions:

1. Does this information give any clue as to the cause of my crash?
2. What command line options should I be running with DUMPCHK.exe to get the proper results. The following command line options are available:

==============
DUMPCHK [options] <CrashDumpFile>

-? Displays the command syntax.
-p Prints the header only (with no validation).
-v Specifies verbose mode.
-q Performs a quick test. Not available in Windows XP.
-c Does dump validation.
-x Does extra file validation; takes several minutes.
-e Does dump exam.
-y <Path> Sets the symbol search path for a dump exam.
If the symbol search path is empty, the CD-ROM
is used for symbols.
-b <Path> Sets the image search path for a dump exam.
If the symbol search path is empty, %SystemRoot%\System32
is used for symbols.
-k <File> Sets the name of the kernel to File.
-h <File> Sets the name of the HAL to File.
==============

So... any help anyone could offer on this would be most appreciated.

I'm not a technophobe and I guess it's time I start to learn about this stuff.

Thanks in advance...!

Hello and welcome to Techspot.

You`d be better off using the winDbg programme, it is part of the Windows debugging tools.

Look at this short tutorial on how to read minidumpsHERE.

You might want to go HERE and follow the instructions.
