I think it's time to ask for your kind help.
I was using an Asrock N68-GS3 UCC mainboard with an Athlon II X2 proccessor. Opensuse 12.1 KDE (64bit) was installed and everything was as it is in a fairytale. One day, I decided that it was time to move on a more powerful processor, like the AMD FX-6100 6-core. I needed another MB, so I picked up a N68C-GS FX, which had the same chipset, plus an AM3+ socket. The new processor was in the supported CPUs list.
Ever since, no more network for me and no more power off or restart.
So, I procceded for a new installation, from the same, above mentioned DVD. Same thing. No network connection and when I try to shut down, at the end of the proccess, after the disk's parking "click" is heard, the MB stays ON and the fan and everything and the screen displays a melted version of whatever it was displaying last time. No matter if I shut down from the K menu or from konsole as root with "shutdown now".
The router (Huawei HG520C) is wired to the PC we talk about, an Access Point and to a media player. Of course, tried disconnecting all of them, even restart the router. Maybe next day I'll try to use another router.
The same PC has a second boot with Windows, working OK. Honestly, I use them once or twice a year. Even after the MB has been changed, windows works flowlessly, without any new installation.
The DVD used for the 12.1 installation is the very same used some months ago for my installation, also used for my other computer at
work a few days ago.
I also tried out, with no luck:
1. Opensuse 12.1 Gnome live (64bit)
2. Opensuse 12.2 KDE live (64bit)
3. Opensuse 11.3 KDE live (64bit)
4. Suse Linux Enterprise Server - hard disk installation
5. Mint 13 Cinnamon - live
6. Mint 13 KDE - live
7. Cent OS 6.3 DVD
Although onboard NIC RTL8211CL seems to be correctly recognized, no data comes from my router, in all cases.
Lately, I have installed openSUSE-12.2-livecd-kde
