Lan drivers  

I found more about Core 10 error here. It say that you may try to restart your pc. So try restarting it...

Try this....Contol Panel/Network and Sharing Center, in this window click trouble shoot to see if it will fix it. If not, it may give a clue to something else.

It seems that your BIOS update messed things up. I don't think this can be fixed by updating W7 stuff. We need to get the BIOS recognition first....

Did you update BIOS to P5KPL-AM 0603 BIOS 2010.08.26 update?

Are you sure that BIOS update finished correctly?
If in doubt... retry the whole procedure form the start:
1. Bios update: ASUSTeK Computer Inc. - Motherboards- ASUS P5KPL-AM

2. after correct install of BIOS, the FIRST boot you do: do in Safe Mode and install the ASUS supplied LAN driver for this board: Realtek RTL8111/8112 LAN Driver V7.3.522.2009 for Windows 32/64bit 7.

Here (too): ASUSTeK Computer Inc. - Motherboards- ASUS P5KPL-AM

You can of-course already have downloaded that update / driver beforehand so you have it ready for that first boot.

Hth..

I did everything as you said... re installed bios, went in safe mode, installed drivers, but still nothing...
When i start PC lan lamp is glowing, so i think its not hardware.

glowing or does it flicker (go on and off continuously)?

No its working like it did before (glows), also i can't find mine there, but its P5KPL-AM SE. :)

Glowing is not right... the green should glow and an orange should flicker.

Is there some way that you could check a couple of things in the hardware? For example:

Plug the LAN cable that now goes into this computer, into another PC/LT to be sure that connection works?

Add a simple lan card to your current system and see if that does run on this cable?
