Jmicron Wired NIC suddenly dies

here's the situation guys.

yesterday, my PC hangs and after I reset, the NIC is not connected, as if it does not have a network connection, which is usually connected as my connection (physically) is always connected.

after some test, I've discovered that if my PC is connected to my wireless router through the wired connection, it's not working(used to work), not even in switches anymore,
The only setup I've got a connection is when I connect my PC directly to my ADSL router, or if it is connected to another computer (PC-PC connection).

my concern is that, I need to be connected to my home network.

these are the scenarios I've tested :

*Directly connect the PC to ADSL router (work)
*Directly connect the PC to another PC (work)
*Connect the PC to a wireless router (don't work)
*Connect the PC to a switch (don't work)
*Changed cables then connect the PC to wireless network or switch (don't work)
*Connect another computer to the same port,same cable, same router and switch (work)
*Connect the PC to another wireless router and switch (don't work)
*Connect other computer to another wireless router (work)
*Reformat PC to Windows and after installing LAN driver(don't work as soon the driver is installed)
*Tried Linux live CD(don't work)

I've tried 4 different wireless routers and a switch in these tests.
and even tried flashing the BIOS

One more observation
from total shut-off (cables unplugged) as soon as I plug in the PC, the NIC LED is lit(connected to the wireless routers). but, after loading the OS, the LED became unlit.

as I conclude, it is a hardware issue.
do it need a flash? or something else?


HARDWARE SPECS:
MOBO : ECS G41T-R3
NIC : JMicron PCI Express Fast Ethernet Adapter

as I've checked resources tab

the resource settings has these values.
