Windows 7 Blue Screen of Death - while cionnecting to Tata Photon Wi-fi

Hi,
I am using 32 bit windows 7. When I connect to Tata Photon Huwaei Wi-fi, I get a blue screen with the following message. Earlier I was using 64 bit windows 7 and it was working fine but all of a sudden it started showing blue screen on various accounts so I re-installed windows 7. Now this again has started showing blue screen of death. Kindly help
