Windows 7 - Network cards missing in Network Center (not in device manager)

Hi there,

recently I've swapped my motherboard, cpu, memory etc, but not my HDDs.

I'm using the very same OS now as prior to the motherboard change, but never noticed that the network card(s); connection status(es) in the network center are missing:



But they are visible in Device Manager:



I can't access the network card settings at all and when I go to Network Card Advance Settings this shows up:


I must admit that I was overclocking my new system and the OS crashed several times until I got it stable :P

I'm not really sure when the network cards disappeared in the network center, but I am kind of hoping that I can fix it.

Also today I decided to install the service pack 1 hoping that it will fix it, but it didn't.

Please also note that for some reason my Bluetooth tray icon doesn't come up anymore, though it still works - meaning I can still connect my PS3 DualShock3 controller with my PC, but there is no settings window or anything like that in the control panel regarding bluetooth.

Any help will be much appreciated.
