Windows 7: Network drop (bad localhost ping) under 7-64bits

Network drop (bad localhost ping) under 7-64bits

Hi,

First at all please excuse me for my english as it's not my main langage.

I have some troubles with my network connection under Windows Seven. Often (usually while surfing on internet) my connection drop. First I though it was because of chrome but it's not (I tried ie and firefox).

Today I tried to change my dns thinking the problem was from my ISP (used the free google dns) but nothing worked. I then tried to disable the card to re-enable it thinking it could change something ... and that was the mistake !!
Once I clicked on disable, the system worked for like 10 minutes to success and it was even longer to reactivate it. I the tried to reboot, the system worked for 15 minutes before to be able to. Go on the "network page setting" (don't know how to say in english) could take 10minutes too !
Anyway, after some disable/enable tricks, all "seemed" to be back to normal. But after some times the connection droped again. I cheked my (windows) firewall, disabled it, did same for kaspersky and the problem was still there.
I tried to ping Ip outside my local network, not working. I then tried 127.0.0.1 and IMPOSSIBLE to ping !!!

I wanted to reboot and during the process to stop the system I got a blue screen (minidump log are there Free - Envoyez vos documents).

After the restart I tried to ping again 127.0.0.1 and here is the result. I don't get why it's not consistent ...

I have no idea what is going on and what to do. My drivers are up to date, could it be a bad motherboard ?

Here is my ipconfig

Note : Recently I noticed my VIA audio desk application popup thoses messages all the time : "Jack unplugged" .. "Jack plugged" ... "Jack unplugged". And no I don't touch to the audio cable. Could it be that the audio hardware is giving trouble to the ethernet nic ?


My system info :

Windows Seven 64bits
Motherboard Asus P7P55D
Core i7 860
4Gb RAM
2x500Gb Raid 1


Any help is welcome

Regards,

Sebastien

Due to being unable to ping local host this means busted card. If it's an on board card, which it sounds like it is, it could be due to a dying motherboard. I've never seen this caused by "bad drivers"... but that doesn't mean it's not possible.

You can first try updating your nic driver. Also verify that the tcp properties are set correctly. Preferably dynamic.

I would change your dns server to your dhcp / gateway address as well for testing.
