Computer shutsdown when repairing Wi-Fi?

Ok, so my co-workers computer Wi-Fi stopped working, and he had no idea how to fix it. So i went over and right-clicked the symbol in the bottom right, and after telling it to repair itself, it ran into an error and instantly Shutdown. The moniter sat there in "standby mode" and the computers power light was flashing green.
We restarted it and the Wi-Fi was working o send the erroe report, but about a minute later the Wi-Fi dropped again, and instead of having it do the automatic repair, i manually disabled the card, and while "enableing" it again crashed when an error popped up.
No matter what USB slot we have the adaptor in it seems to cause this sudden shutdown.
I have no idea what could cause a shutdown while repairing the Wi-Fi. This is the first i've ever seen of this.

Specs:
Computer is IBM Thinkcentre with Win XP installed.
Wi-Fi card is Linksys Wireless-N USB Adaptor (N300)

When an external device appears to cause the system heartburn, I start thinking that the device driver for that piece of hardware is either the victim or the cause. Try downloading a newer version of the adapter's driver, if available.

If that doesn't work I'd look at the System Restore logs and see if you have a checkpoint that's a couple weeks into the past. Since you're running XP that may be wishful thinking (since most SR checkpoints are done prior to apply MS maintenance).

Buena Suerte!

It sounds like you are describing the computer instantly rebooting, is that correct? Shutdown implies that the OS went through its shutdown process first, but you make it sound like it did a hard reset. If that's the case, then there's probably a hardware issue causing a short some where. Unless someone else has a better idea, I would recommend taking it to PC repair shop.
