Hello. Specyfication of my Notebook:

Notebook Clevo P170EM

Intel(R) Core(TM) i7-3630QM CPU @ 2.40Ghz

16 GB RAM Corsair Vengeance DDR3 @ 1600mhz

NVIDIA GeForce GTX 675MX

+

Belkin ScreenCast TV Adapter for Intel WiDi

My Widi works fine (just games dont work's on tv but this is not important for me). The problem is with drivers.

Im using old graphic drivers, old drivers to my network card and soundcard.

If i do a update of any of these:

WIDI Software

Intel(R) HD Graphics 4000

Intel(R) Centrino(R) Ultimate-N 6300 AGN

or Realtek Soundcard

My widi stop working. I cant connect or i dont even see my screencast in widi software. After backup to old drivers or software, widi works again.

Any solution?

I dont want to use old drivers all the time...

My Windows have all updates

Firewall been switched off

I dont have ant viruses or spyware
