No Network Adapters showing in Device Manager

Hello all,

maybe someone can help me with this strange issue:

i've just upgraded my graphic card and now i don't have any network adapters listed in the device manager (only firewire under +IEEE 1394 and all the other devices)

I've already reinstalled Windows 7 (64 Bit) and tried installing another LAN card (10/100) - that wasn't recognized.

Within the BIOS (award- Motherboard- GA-P35-DS4 ) i couldn't find anything related that should be turned off/on?

Could it be broken if it is not appearing there?
If yes- why isn't the motherboard recognizing my other LAN Adapter that i've installed on the bottom slot

Should i reset the Bios by pulling the battery/using the cmos jumper? What else could be the problem?

Thanks for any tips / help

Try this

Boot in safe mode
Remove NIC from device manager
Remove the NIC and any other cards you have
Reinstall NIC only! (use motherboard graphic card if you can, otherwise put it back in)
Install drivers

Second thing to try

goto Start > RUN > CMD > and type msconfig

Uncheck everything in startup and reboot and see if it works.

If it does work then the problem was a application running that was conflicting.

Have you had any bad storms or power outages lately? NIC's are easy targets for power surges..

first of all, thanks for your answer.

I've already resinstalled Windows - as i mentioned - no network adapters are listed in the device manager.
Its onboard and also not showing in the bios (was there before)
I've cleared CMOS using the jumper and pulling out the battery - nothing worked.

I think its dead (maybe i should try a BIOS update as last thing)
Now i'm using an wireless usb adapter to connect to my router.
