BSOD problem

hello!please help me and i shall be very glad,about 6 months ago i formatted my laptop and it had sound before then, but after the formatting and up till date i have never had a sound driver for my laptop..when i install realtek it produces the blue screen with error codes telling me windows has shut down to prevent your machine from damages..i have used so many drivers type sound max and all the rest but vinyl 97 produces the sound icon but yet no sound, driver pack will always try to update it but the blue screen will appear.it is a sony viao VGN-AW170YIQ laptop...though when i run some softwares they identify the machine as NEC.
thanks again as you help me.:cry

 

The Sony support for page for your model specifies Realtek audio.

Uninstall your audio device via Device Manager, then reboot and install the proper Realtek driver.
