Yesterday, I cleaned up my pc and both onboard realtek network adapter and realtek audio adapter are stopped working. (I've removed the nvidia geforce 8400gs graphic card and using onboard graphic card). I tried with Ubuntu live CD and audio (only right side of speaker) is working. Speaker is working well. I've tried with my phone. LAN doesn't work on both windows and ubuntu eventhough I can see the orange light at LAN port.
I've reset the CMOS setting by removing battery. Install drivers from driver cd came with mobo eventhough not compatible with windows 8. But it worked without any problem after first windows 8 installation. It just stopped working after I cleaned up the pc. I've also refresh windows 8 and still doesn't work.
Mobo is Asus p5kpl-am/ps.
Any advice would be greatly appreciated. Thanks.
