Annoying noise like radio, hear while windows 8 boot load

[farhang_760]

Hi
Few days ago i have a clean install of windows 8 on my Vaio - VPCf23efx/B - and faced with some problem like, Loss of battery care function, smart network, backlite led management and ...

I am not worried about it, because the company informed this before, but one problem that I faced with and couldnt understand why??, is that when turning on and windows 8 boot loader appears after a few turns of load circle!! I hear an adverse sound like radio speaker noise! for a moment (1 sec.) .

Note :

I use Vaio Upgrade tool to install all of my driver and Device manager doesn't detect any undefined driver.

I hear this annoying sound after any turn on process that boot loader appear, Also after sleep and hibernate process.


Pleas Help me.
Thanks a lot

I suspect. its because your Ethernet card is using full duplex, try going into the card properties and go with half duplex. How's it going Mr Farhang
