Are you by any chance running this card in half-duplex mode? If you were connecting to a hub (rather than a switch) and all of your network was running half-duplex, then that level of collisions wouldn't be particularly remarkable. However nowadays basic 100Mb switches are cheap, so that would be rather unusual. However, a card that fails to autonegotiate with the switch will fall back to running at 100-half. That's generally pretty obvious because performance will be abysmal. Other alternatives are hardware problems -- try a different ethernet cable. Try plugging into a different port on the switch. Try a differen= t computer on the cable etc. where you're seeing the problems. If none of that identifies a fault in the cabling, then it's looking more likely tha= t your network interface has gone fubar.
