I have sony vaio laptop, when i tried to connect to the internet using WLAN its giving a blue screen with an error message: "hardware malfunction, contact vendor" and i need to reboot my laptop.But if i disable WLAN and connect through my LAN my laptop is working alright. So i got an external wireless adopter and tried to connect to the internet after disabling WLAN but when i try to do it my new wireless network adopter got disabled automatically. Is it a hardware conflict or some other issue. I am not able to figure it out whats with my wireless, could someone suggest me a solution for this. Always it will not be possible for me to connect to LAN and my laptop warranty got expired.
