Upon start up, she keeps getting the BSOD with:

"A problem has been detected and windows has been shut down to prevent
damage to your computer.

IRQL_NOT_LESS_OR_EQUAL

If this is the first time you've seen this stop error screen, restart
your computer.  If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly
installed.  If this is a new installation, ask your hardware or
software manufacturer for any windows updates you might need.

If problems continue, disable or remove any newly installed hardware
or software.  Disable BIOS memory options such as caching or
shadowing.  If you need to use Safe Mode to remove or disable
components, restart your computer, press F8 to select Advanced Startup
options, and then select Safe Mode.

Techinal information:

***STOP: 0X0000000A (0xFF1701F0, 0x00000002, 0x00000000, 0x804D9B64)

Beginning dump of physical memory
Physical memory dump complete.
Contact your system administrator or techinal support group for
further assistance."

She hasn't installed any new software/hardware.  System Restore has
not helped.

What I know so far:

When in Safe mode, the machine loads most applications fine.  Word,
Excel, Picasa...
When in Safe mode, Device Manager (show hidden devices) shows no
question or exclamation marks, not even in Network Adapters.

When in Safe mode with Networking, she gets the BSOD again.  This
leads me to believe there may be a networking adapter/driver issue.
Under Network Adapters, the Device Manager shows many devices, but the
main ones are:

Broadcom 440x10/100 Ethernet...
Intel Pro Wireless 2200 b/g

My first thought is to Disable each of the above, one at a time, and
see if the machine will boot up normally.  If not, then Uninstall each
one, one at a time, and see if the machine boots up normally.  If so,
I guess I need to reinstall the network drivers.

She has none of the Dell repair/utility/driver disks with her.  She
does have access to another pc so she can download from the Dell site,
and move to her machine via flash drive.

If it turns out that the Intel Pro Wireless driver is corrupt, and she
doesn't have the disk to reinstall it, I wonder if I can install the
Wireless Zero Configuration, which should be on her hard drive.

Does this approach sound reasonable?

I've seen the tools for analyzing dump files, but that's way beyond my
capabilities.  I have to use a sledge hammer rather than a scalpel.

I had my daughter drive to the end of the street and turn on her
laptop.  It worked fine and didn't BSOD.  She then drove back, got out
of the car, still with laptop on and doing fine.  When she went into
her apartment, it BSOD'd.

I've had the apartment set up with a Linksys WRT54G for a long time.
Last Saturday, one of the roomies wanted to swap out the Linksys G
router for a Linksys N router, to increase speed for gaming.  The
consensus was not to swap it out, but just connect the N to one of the
LAN ports on the G router.  This coincides with when the BSOD started
to happen, when my daughter got back to the apartment for the first
time since the N was set up.

I've asked her to turn off the N router, and see if she can still
connect to the G router.  If so, we'll have to decide if we want to
install the Windows Zero Configuration and see if that works will
work.

I sort of think it's asking for trouble having two wireless
routers,turned on, sitting on the same table, sending out signals.
But I'm no expert.

Boris, first of all it's been likely 5 years or more since I've had to
mess with IRQ's so my memory isn't too good on this but as I recall,
IRQ conflicts are due to bad or conflicting IRQs for hardware
installations.  Sometimes the hardware will be flexible and allow you
to pick the IRQ.   Like I said, I'm a bit fuzzy on this since it's
been a long time since I've messed with IRQs.  I think the router
should have no bearing on IRQs but I think you might be on the right
track to suspect the network card.  I guess for starters I'd uninstall
the driver for the wireless(??) adapter and then remove the wireless
card.  Then reboot, install the adapter (use a different slot then the
original if available), then re-install the drivers.  If this doesn't
work, I'd have to check google or think about it after seeing what and
when the error message occurs on the screen.

Likely others will be more fresh on IRQ conflicts or just google for
IRQ conflicts.

My daughter just wrote:

"Hi Dad!
I went outside near the apartment office and my computer turned
on fine and was able to search for wireless signals. I actually
connected to one too and it worked. Also, I asked 'roomie' to turn
off his router and then I turned on my computer, and what do you know
it worked! Then I plugged his router back in with my computer still
turned on and it went back to the blue screen. Seems pretty
convincing to me then that it's the router. Just wanted to let you
know. Now that it works in here with his router off I could even
download whatever it is I will need from here to reinstall the driver
as long as he's not using it."

So it seems that there's nothing wrong with her adapter or driver, and
she should ask roomie to be sure that his router has updated
firmware. If her wireless and his router still don't play nice, then
we may try replacing the Intel Pro Wireless with the Microsoft
Wireless Zero Configuration. We just want everyone to get along.



I know this is a moot point but I just realized if this is for a
laptop, you can't move the wireless card to a different slot. For
some reason I was thinking of a pc. Brain going dead.

Anyway you likely found the cause or near cause now.
