Wireless Network Causing Crash

After many hours of investigations & testing, I've narrowed down the cause
of sudden crashes of my XP Pro Desktop computer to a Wireless issue.

The desktop simply cuts out as if the power supply's been pulled. I've
eliminated all sorts of likely causes (despite error codes suggesting
graphics cards, I'm 99.99% sure it's not anything to do with that - still
crashed after all drivers uninstalled) and now I've reached the stage where
I can actually cause the crash to happen: All I have to do is go to My
Network Places on the desktop computer and attempt to access any file on my
Laptop - bang, not immediately, sometimes it takes a minute or two, but
without doing this the computer *never* crashes!

I have a small (4 machine) network via an ADSL Wireless Router. All machines
have fixed IP addresses and previoulsy communicated without problems.

The desktop machine is based on an ASUS mobo with built in Wireless - I've
got the most recent drivers for everything.

Any ideas as to what to do next?

Hi
Thousands of hours with Wireless using more than hundred various devices,
never experienced such a "story".
My Conclusion it is the Asus Wireless Client, I would try Asus support
first.

Hi,
The above were all things I investigated during the "many hours" mentioned.
As it turns out, even after a complete reinstall of XP Pro, the problem
wouldn't go away. This computer runs perfectly and even connects to the
network via cable without problems. When I open a window to the network via
wireless however, it crashes very soon after.
An interesting problem, but I don't have time to mess around with it any
longer. I installed a PCI wireless card and that works fine.
Conclusion: Obviously directly related to the Asus onboard wireless (which
as I said, has worked perfectly well until recently).

Thanks, you could well have been right Jack. Didn't have time to investigate
any longer. Still same after reinstalling XP (see details in other
response).
Now working fine with a new PCI card and onboard wireless disabled.
BTW in regard to your never having heard this before. I posted simiar
requests in many locations and at least half a dozen others had similar
issues (none with Asus onboard however).
