Ok, my problem is the following: After starting L4D, Steam said my GPU drivers arent the newest. So I downloaded the latest from Nvidias HP. But, they said before installing new drivers, I should deinstall the old ones before.

Im using Vista, so I went to "System Control(?)" (Systemsteuerung in German), searched for Nvidia (as descriped on the Nvidia HP), and the thing it found, I double clicked. I chose "deinstall all drivers, including Display (below there were standing all the drivers I would deinstall, something was standing with ethernet, but I just clicked ok (yeah it was stupid I guess)).

After deinstalling succeeded, I rebooted the PC, installed the new drivers, rebooted again, and it worked.

Only issue Ive found so far - I cant connect to the internet (Im writing from another pc here).

I dont know what to do right now...

Ive checked the "device-manager(?)" (Geräte-Manager in German).
Issues with drivers appear here:
Other Devices - Unknown Device (Driver not installed) (Code 28)
Network Adapter (Netzwerkadapter) - 6TO4 Adapter - Driver is installed, but Windows cant load it. Code 31
Network Adapter - isatap.{7AAF81AD-D7C2-493C-B9F8-A18795C2CAB3} - Driver is installed, but windows cant load it Code 31
System Devices (Systemgeräte) - Nvidia nForce PCI System Management - Driver isnt installed
System Devices - Nvidia nForce System Management Controller - Hardware Device cant be started cause Configuration Informations (in the registration) arent complete or are damaged (Code 19) (I translated this myself)

I checked Google for several things (what is nvidia nforce management thingy), but I couldnt find a solution so far...

Another thing I mentioned is, normally, when I click on the 2 computers in the bottom right corner (the network icon thingy), there stands "connected to: network (only local)" (when not connected to the internet).
But right now there stand "not connected" to anything. It also doesnt say something like "No LAN-Wire(?) (LAN-Kabel in German) connected)" and it seems the pc doesnt recognize if i stick the LAN-Wire(?) in.

Anyone can help?

Regards, Relentless

Hi,

It looks like to me you are using a NVIDIA chipset aswell, and you accidently break those drivers when wanting to de-install your GFX drivers.

Check what chipset you have on your motherboard, and download the driver (nforce i think) package on www.nvidia.com.

It seems there more than just one nForce series...

How do I find out which chipset I have (the exact name I mean)?

Tried with a program called WinAudit that I found with Google, but it cant tell me.

use cpu-z, run it and open the mainboard tab for chipset infos

http://www.cpuid.com/cpuz.php

Okay, checked with cpu-z. It said:

Chipset NVIDIA GeForce 7100
Southbridge NVIDIA nForce 630i

And this one is indeed on NVIDIA's homepage! (http://www.nvidia.co.uk/object/nforce_6 ... 08_uk.html)(But instead of .co.uk i used .de)

But, again they tell me I should deinstall my GFX drivers first. So, that means in the following order:

1) Deinstall GFX Drivers
2) Install nforce thingy drivers
3) Reinstall GFX Drivers

Is that correct? (I rather ask twice before I break my PC even more)

yeah, uninstall gfx drivers, install the nforce drivers and before you install the new gfx drivers (geforce 178.xx is the latest version with geforce 7 support if i remember right) remove the old gfx drivers, BUT ONLY gfx drivers, leave the rest untouched, reboot and install the new geforce drivers

Hooray it worked

Thx for the help guys. See you on the servers soon

PS: L4D doesnt cry anymore about old drivers, so at least I got something from this torture
