Deus Ex Alpha

Hi all. Im posting about a packetloss problem in DeusEx. (and unreal for that matter).

We had a power outage, and upon power returning went for a game of DX.

50-80% packetloss at all times. Its only on this PC. Its wireless is fine, but with ethernet it does this. Im starting to think a small surge may have trashed the ethernet card (please no, onboard the motherboard).
No other faults have occoured. I dont have a spare ethernet card to try, (an old ISA one, but NO ISA SLOTS HERE!). Voice chatting is also extremely dodgy, assuming because of lost packets. This PC i built myself,not a single problem until today. I do take the following precations:
Surge protectior, Ground fault interrupter outlet (the protecter was like £40 itself), Good quality powersupply, phone line surge protection. (my parents dont know crap about this, i do all this stuff )My server machine is showing no ill effects, and DX works without flaw on it. Narrowing it down. P.S The motherboards warrenty expires in feb. I can replace it, but i dont want to waste time unnecisarily. Also ive tried Clearing CMOS, removing all non essential expansion cards. Any other stuff you suggest i try?
Many thanks.

Did you have the ethernet cable plugged in when you lost power?

Make sure it's not the cable itself that is damaged

Try the cable elsewhere

Did you have the ethernet cable plugged in when you lost power?

Yeah i did.

Also i tried the cable on the server machine, it works fine. No problems there

you could just pick up either a USB to Ethernet Or a PCI to Ethernet card so u dont have to pick up a new motherboard

Yeah ill do that instead. But as MBs under warrenty mightaswell get it replaced. I looked very close, and i see visble charring and scorching. You have to look very closely. its around the ethernet socket. So ill just take the motherboard for a replacement. Many thanks for all the help guys
