Hi,
I think these problems are very similar to my problem which I mentioned in this thread:
http://forum.giga-byte.co.uk/index.php/topic,3927.0.htmlI also use the "solution" with unplugging the cord and then plug it again and trun the PC on. I also wrote to GIGABYTE supprot and they replied:
"About the issue you mentioned, please first install the latest LAN driver then try again later. And the USB ports and PS/2 detection problem, please follow the steps below taking off the on-board battery to leak voltage to clear CMOS then try again later.
1) Turn off power.
2) Remove the power cord from MB.
3) Take out the battery gently and put it aside for about 10 minutes or longer. (Or you can use a metal object to connect the two pins in the battery holder to make them short-circuited.)
4) Re-insert the battery to the battery holder.
5) Connect power cord to MB again and turn on power.
6) Press DEL to enter BIOS and load fail-safe defaults setting.
7) Save changes and reboot the system.
But, If the problem still occurs, then there may be a problem with the BIOS. A further testing or examination to your system might be required. We suggest you to contact your supplier for further assistance to see if they can help you do further testing on the system. If they cannot help you, please contact us again and we will try our best to see how we can assist."
I will try it but I am not sure it will help...
It looks like that this problem does not occur if I turn off the PC from safe mode (it is of course not usable as a solution better then unplugging the power cord but it looks like that could be caused by some driver/utility which is not used in safe mode and which, when the PC is shutting down, does not end end working with network adapter correctly. But I tried thi only about 5 times so I am not sure if it really never occurs.) As you probably know, all the peripherals with which we have problems (network adapter, USB) are connected to ICH10 southbridge.
I have BIOS version FB.
