Wmi files missing or corrupted

Hello, I have a dell inspiron 531 desktop comper running windows xp service pack 3. It has an amd processor and a nvidia ethernet card. Lately I am having all sorts of problems trying to get it to work right. My network connection is not working and I am having problem installing software completely. Every error that I get seems to have something to do with my "windows management instrumentation" files missing or corrupted. I haven't been able to repair my network yet, so I'm figuring that if I repair my wmi files then maybe I can fix my network. I've tried the wmi utility but i ready didn't understand what I was suppose to do. Please help me repair my wmi files. Thanks

 

Thanks major attitude! As far as I know, that solved my wmi problems. Now I'm trying to get my network connection back. Thanks again

 

@ major attitude, unfortunately my computer has a built in Ethernet card. I didn't have the option to delete the card, so I deleted my connection in the my network settings. Then I tried to uninstall the drivers. That was the last thing that I could do with it. now when I go to it in device manager and right click on the Ethernet card, it does not respond. It shows an exclamation mark in the device manager. I have tried installing a wireless adapter but haven't had any luck yet. When I try and setup a network, it does not recognize my network hardware

 

Did you download and install the latest driver for your Nvidia card from http://www.nvidia.com/Download/index.aspx?

After doing that, do you still have the exclamation mark on your network adapter? If so, right-click | Properties: what is the error?

 

@ pwillemer
Yes I have tried that but I think that I have some other issues going on because my system is not letting me complete any downloads. I don't know if it is a windows installer problem or because I only have 5 gig left on my hard drive. My computer is also not installing new hardware that it finds. I disabled the ethernet card from within the set up screen. I tried to install a wireless adapter but that didn't work because I couldn't get the software to install. As always, thanks for your help

 

In response to your question, yes I still have the exclamation mark and I don't get an error when I right click on it because it does not respond

 

Still need help. I have an onboard nvidia Ethernet card. Recently, I have been unable to connect to the internet. When I open the device manager, I have exclamation marks on my mouse, keyboard and ethernet card. My mouse and keyboard actually still work but my ethernet card is not working at all. As a matter of fact, the task manager keeps telling me that I have "no active network" adapter. I have already tried uninstalling but that didn't work. I get no response from the device manager. I have even tried to put another ethernet card in and have even tried wireless but I can not get the software to fully install. I have learned from reading that I have to delete something in my registry so that I can uninstall it. I don't want to screw up my registry; therefore I and trying to get some step by step instructions. Please help if you can! Btw, I am running windows xp service pack 3 with an amd processor. The computer is a dell inspiron 531 (desktop). Thanks
