But as a final test since these are related to the TCPIP stack lets see if we can stress the tcpip and force your computer to bluescreen.
This is service pack one for 64 bit windows 7 you do not need it but lets see if we can make the crash happen again after the fix I suggested.
This is the file I would like you to download.windows6.1-KB976932-X64.exe

Sourced from here.

Do not worry you can delete it later I just want to test the machine.
Also while you are downloading the file can you run this test at the same time in a different window please we are going to try and stress the connection.

Let me know if it crashes.
If it will not crash while doing this then I think all is well.
