Can you think of anything you might have done that caused the problem?
What devices do you have plugged into your USB ports?
Try reinstalling the wireless drivers and see if the problem still persists..

Ah... so it sounds like a hardware issue... more specifically a power issue with the WiFi card causing it to draw too much power...

Try taking out your charger, taking out your battery,  leaving the laptop alone for a few minutes, and power the laptop on with only the charger (no battery inserted) with the wireless switch off and without any USB devices inserted. After windows fully boots, then turn on WiFi.
