  1. If you update the OS from 32 bit to 64 bit, ALL the drivers for your various hardware devices must also be updated to 64 bit too, did you do this?
  2. yes i did and still this is the only drivers that makes probleams with 64 bit
  3. Did you use the Windows default drivers, or get them from the manufacturer's website? The latter is far more preferable because it’s less likely to produce these kinds of problems.
  4. yes i downloaded the drivers from intel website
  5. From here?

    Does the ethernet card show up under Device Manager->Network Adapters (Window key + R, type “devmgmt.msc” (no quotes), hit enter)? If so, does it have a yellow exclamation mark next to it indicating the driver isn't installed or working properly?
  6. yes i downloaded what you link and it appear green onn device manegar.
