Hello everyone,

After 6 hours of reading/testing I can't do anything else and I am really tired, so you guys are my last hope. Here is the problem:

I had a lot of hardware in my stock so I decided to make some desktops today. I built them normally without any problem, the only thing was that in 1 desktop I had to use DDR2 ram instead of DDR, so I borrowed one ram card (2GB) from my main PC in order to make the desktop run.

While I was making a format to my desktops, I tried to log in from my main PC. Then I face out the problem: I couldn't connect to internet!
- It says: "no connections available"
- After troubleshoot: "Windows could not detect a properly installed network adapter"
- When I installed the latest drivers: "The realtek network controller was not found. If Deep Sleep Mode is enabled Please Plug The Cable"
- In device manager there are no "Network Adapters" anymore, only in hidden, and I can't update/reinstall them.

I tried the following I read around:
- Unplug everything from PC and wait around 10 minutes, then plug them back.
- Safe mod uninstalling drivers and reinstalling them. Same error.
- Bring back my RAM and run. Same error.
- Restore default BIOS settings. Same error.
- Add a network card (not sure that it's working, it's an old one). Same error.

Please note that the other desktops are running perfectly. I am asking for help since I can't do anything else, and I feel helpless. The only thing left is to format my PC but I am not sure that this will solve the problem and it's my last solution.

Waiting for your replies..
Thanks!
