Overclocking overclocks the PCI bus, so perhaps the Ethernet card doesn't like the extent to which it is overclocked. Try using theproper clocking settings.

 

I thought he said he set his BIOS back to Failsafe settings, so the OCing would be gone, but that was a good point. Can you replace the cable from the PC Lan port to the wall LAN socket? Do you see 2 lights on the cable port when you plug into the mobo? My 2nd connection which goes up to the kids PC does this to me sometimes. I just wiggle the crap out of it and eventually I get it again. Happens every few weeks. I know I need to replace the end connector but keep forgetting to borrow a crimper tool from work IT dept. If you replace the LAN cable from your PC you'll need a crossover cable.

 

You can 'break' devices by overclocking. I bet he fried his ethernet controller, thats ok though. Putting a regular PCI card in rather than onboard shouldn't cost more than $10, really it shouldn't cost more than $5 if you've got a friend or a computer shop near by. I'll sell you one of mine for $15 + Shipping

 

Yea I have tried a different cable and I have also wiggled it around alot.

I have about 6 of thos ethernet cards aqt home, I will try one as soon as school lets out.
