Re: Driver IRQL Not Less an Eaqual!!
How long did you permit the Driver Verifier to run? It could take >>
days to get to the point of re-creating the events leading up to the
BSOD, if even possible. What settings were applied to the verifier? MS
drivers should not be verified - no need. If BSOD is software related,
it must obviously be a kernel mode driver. The driverquery would be
helpful in a search for out-dated drivers.
As I mentioned, I will run the dump(s) and post the results here. It is
your call. Dump files are in \windows\minidump. I would also like the
driverquery text file along with an msinfo32 NFO file (default file
extension). Zip them up and attach to post. Who knows what may be there.
I asked about Vista vs. XP b/c it matters when running SFC. I would
advise doing just that. If Vista, no DVD required whether SP1 or not.
You are Vista SP1 updated... right? XP sfc needs slipstream XP CD.
As for the Driver Verifier - try it again - but using the following
(Vista instructions): Bring up an *Elevated* command prompt -
*START | type cmd.exe | right-click on cmd.exe uptop under programs |
Run as Administrator | type *verifier* & hit enter - the Verifier screen
will appear | do the following:*
Code:
--------------------
1. SELECT 2ND OPTION - CREATE CUSTOM SETTINGS (FOR CODE DEVELOPERS)[/B]
*2. SELECT 2ND OPTION - SELECT INDIVIDUAL SETTINGS FROM A FULL LIST.*
*3. CHECK THE BOXES -*
*• SPECIAL POOL*
*• POOL TRACKING *
*• FORCE IRQL CHECKING*
*4. SELECT LAST OPTION - SELECT DRIVER NAMES FROM A LIST *
*5. CLICK ON THE PROVIDER HEADING - SORTS LIST BY PROVIDER*
*6. CHECK ALL BOXES WHERE MICROSOFT IS NOT THE PROVIDER*
*7. CLICK ON FINISH *
8. RE-BOOT
--------------------
If the Driver Verifier finds a violation, it will BSOD.
For info, some of the more common bugchecks for verifier violations
are:
Code:
--------------------
• 0xa = irql_not_less_or_equal
*• 0x50 = page_fault_in_nonpaged_area *
*• 0xbe = attempted_write_to_readonly_memory *
*• 0xc1 = special_pool_detected_memory_corruption *
*• 0xc4 = driver_verifier_detected_violation *
*• 0xc6 = driver_caught_modifying_freed_pool *
*• 0xc7 = timer_or_dpc_invalid *
• 0xc9 = driver_verifier_iomanager_violation
--------------------
If you would like to see the status of the Driver Verifier, bring up an
elevated command prompt, type verifier - but this time select the last
option on the first screen - "Display information about the currently
verified drivers..". To turn the Driver Verifier off, bring up an
elevated command prompt and type *verifier /reset* then re-boot.
Anything good in the Event Viewer logs (Vista - eventvwr.msc)? Vista
has at least 54 of them. I only look at 2 in XP - the app and sys logs.
What do the events leading up to the BSOD look like? Or do you find an
event recorded similar to ".. the shutdown at 17:49 was unexpected..."?
How is the Device Manager (devmgmt.msc) doing? Problem Reports and
Solutions (wercon.exe) or the Reliability Monitor (perfmon /rel) have
anything to say?
