ThinkPad x61 - Enabling wireless card causes laptop to crash

[hanleybrian]

Hi,

Up until recently, my wireless worked just fine.  I would sometimes disable the wireless card if the wifi connectivity was bad, and use my built-in EVDO cellular modem instead.

The wireless is currently disabled, and for several days now, attempting to enable the wireless will cause the computer to crash.  If I enable the wireless card, I get the so-called "blue screen of death," telling me that there has been a buffer overflow.  Then my computer reboots.

I can't think of any software that I've installed super recently.

Has the hardware probably gone bad?

Or is this likely a software issue?

How should I go about troubleshooting?

Is there some kind of diagnostic that I could run that does *NOT* require me to enable the wifi driver?

I tried using "PC Doctor," but it can't tell me anything unless the wifi driver is enabled.

If the integrated wifi (Intel 4965AGN) has failed, I'll let Lenovo deal with it.  I just wish I could be sure that was the problem.
