8GB DDR3 RAM - 500 GB SATA

MS Windows 7 Ultimate 64-bit SP1

my onboard Gigabit LAN Controller is not detecting stop working.....please give a solution

Have you installed the drivers? Can you see it appearing as an unknown device in the device manager?

If your BIOS is detecting the LAN controller ( try using PXE boot ), then possibly it's a effed up driver that messed itself up in windows - happens quite often.
If it's not showing up in BIOS, then maybe some hardware level problem has surfaced.

i try to install drivers but showing hardware or driver is not found.....how to check this onboard Gigabit LAN Controller is dead or disable...i checked the BIOS setting it show MAC LAN (onboard Lan boot ROM) Enabled

Those are PCI cards. I don't see why those won't be compatible.

Those pci cards can reach a speed upto 100 mbps only.. Get a PCI E X1 10/100/1000 MBIT ethernet card, from iball.. im using one, costed me Rs 400

i want to use my internet cable Connection my onboard ethernet port not working so please guide me

Also try running a live Linux distro say Linux Mint. Is it able to detect and configure your LAN? If yes may be it's driver issue on Windows, else possibly could be some hardware issue as already pointed out by Hrishi.

Check if there are any dependent settings in BIOS/UEFI that are casing on-board LAN to get disabled just in case. By dependent I mean one setting affecting another just in case it may be.

i try to install driver also but nothing happen ...i update BIOS also not working ..i think onboard Gigabit LAN Controller is dead

any other suggestion....?????

Buy a USB wifi dongle and a wireless router. Both will cost you total under Rs. 1000. This is a way better solution IMO.
