Connectivity lost after Windows update

[NedKelly]

Hi guys,

I recently did a fresh install on my gf's computer as it was suddenly unable to establish an online connection. The error showed in the connection status as the small yellow warning icon at the top left of the connection status icon, not the big red X that appears when the machine isn't connected at all.

Here are the specs:

OS: Windows 7 Ultimate x64
Mobo: Gigabyte GA-X58A-UD3R Rev.1
CPU: Intel i7 950
RAM: 12GB Corsair Dominator GT 2000mhz
The system is also not overclocked.

After trying many things (reinstalling network drivers, flushing DNS, trying a different ethernet cable, restoring all network settings to default) I gave up and did a fresh installation.

After installation, I installed all the usual official drivers, then performed a Windows update, but only the important updates. The connection was back! I then decided to install some optional stability updates, and after reboot, the network problem was back.

I did a system restore to before I installed the optional updates, but the problem persists.


Any advice as to how I reverse this? I have no idea which optional update is causing this, or which one to remove first to avoid creating more errors. Any help on this would be great as i've been tearing my hair out all day trying to fix it.

Cheers

Ned

Hiyya Ned and welcome mate you might have to go back even further - or at least I would try that.

For the record I have problems with "optionals" too and leave them if don't need them - leave them there or do them one at a time and leave any with network stuff alone for the time being.

I know this could get tedious maybe you need to start from scratch again and what I do in those cases I don't ever download huge quantities of updates at a time.

NOw you might get lucky with either the update history or the event viewer find two that corrrespond and just maybe you have found the culprit.

Another thing you might try to put on is this Download: System Update Readiness Tool for Windows 7 for x64-based Systems (KB947821) [November 2012] - Microsoft Download Center - Download Details

From another PC download the network adapter driver, save to a CD or USB drive and reinstall on the gf's PC.
Also as suggested, install only 5-6 updates at once, it will work out better and help to pinpoint one if it goes south.
