Dell Studio 1535, vista home premium, Wifi not working in normal mode and giving bluescreen error

Hi,

I am using Windows Vista on dell studio 1535. My WIFI connects to the wireless connection seamlessly in safe mode but in normal mode it gives me blue screen error.

I have installed latest wifi driver and updated my bios to A06 from A05. but still same error.

It doesn't seems like hardware issue as safe mode working great for wifi

Can anyone share how can i fix this issue with out formatting or reinstalling windows?

Thanks a bunch in advance..!
