hi there!

i have recently bought a second hand d 630 which ran just fine on a linux mint. As i was not familiar with this OS, i have chose to instal an windows 7 professional on 64 bit. the system runs fine until i use the wi-fi connection. after browsing about 15-30 seconds, a blue screen appears and the OS restarts. I have tried drivers from dell (although they say  is not compatible with windows 7,  i saw refurbished d630 sold with windows 7 installed). I have also tried drivers from Intel. My BIOS version is A12 but i do not intend to do a BIOS update due to the involved risk

if you have any suggestions, please post me an answer
