weird wireless lan glitch

recently i got a rosewill wireless card for my pc (well because i've wireless internet) and today i rebooted my pc (i've got vista home premium on it) and when it restarted the os i lost my wireless drovers for my card vista started to detect my wireless card as a new device, well i shut down my pc the turned it back on then it detected my card already with the drivers installed (everything is running fine now i just posted this thread to ask if anyone else had something simular happen to them with vista)? LOL.

 

I've had programs loose settings on Windows 7 before but not drivers.
