We just had a quick power outage at work and now one of the computers can't seem to access the internet or network anymore. It is strange because everybody else is ok and this one is hardwired to the switch, just like others and a wireless access point. Can a power outage cause a network card to go bad?
It took a few reboots to get the card to be recognized and now its getting an IP address just like normal but still no internet or network printing capabilities. Anybody have any ideas?

Absolutely. A power surge can fry all kinds of delicate circuits. The two usual victims are the power supply (the surge comes in through the power cord) and the NIC card (the surge comes in through the ethernet cable).
The surge will often affect only one system, since it tries to find the shortest route to ground. The symptoms you relate are classic for a fried NIC. It may fail completely, or partially, or have intermittent failures (as it heats up or cools down short circuits will develop). It can "say" it's working fine, but not be...
Switch the card. 99% certain you fried it.

It's very possible the card was damaged, but there are other places to check as well:
The network port on the switch may be damaged, try another port.
The switch may need to be rebooted.
The driver for the network card may have been corrupted, try removing and reinstalling the driver.
check the network settings and make sure all the bindings are correct (another possible software corruption).
Last but not least, try a complete rebuild of the PC - it's messy and painstaking, but it will confirm if you have a hardware or software problem.

1. Check the light for the NIC in the back of your pc, see if it's lighting/blinking. If it's not then there is no activity.
2. Are you using a proxy? If so, check to see if it is configured properly.
3. Uninstall the device and reboot, Windows should detect it when you restart.
4. Try pinging other PC's to see if your able to send out signal.

Yes, this happened to my mother's computer. After a power surge/outage, her network card was being stupid. So we had to put a spare network card in.

If you're not surge protected, it sure can. It happened to me a few weeks ago and I had to replace the DSL Modem and the card both.

happened to me too---the rep. at AT@T made the mistake of telling me that A POWER OUTAGE-OR IF THEY GO DOWN can fry your system---so I got them to come out free and fix my system-- it was a battle to get them to do it but i just kept pressuring them till they did--i lost all my
network neighborhood---when i clicked on it ---IT WAS GONE!!!!!!! GOOD LUCK
